Subject: [PATCH] Update documentation for style consistency (#2256)

This commit updates most of the documentation set to adhere to some
contemporary documentation style standards:

- Sentence case for titles and headings
- Initial headings for how-to guides as "Overview" and
"Before you begin"
- Moving any frontmatter descriptions to the body of text
- Removing unnecessary frontmatter data altogether
- Removing unnecessary custom style tag (Incorporated
into the theme by default)

It also collapses a few single document directories
(Adding an unnecessary "hop" for users) and re-orders some sections.

 NGINX Gateway Fabric metrics are displayed in [Prometheus](https://prometheus.io/) format. These metrics are served through a metrics server orchestrated by the controller-runtime package on HTTP port `9113`. When installed, Prometheus automatically scrapes this port and collects metrics. [Grafana](https://grafana.com/) can be used for rich visualization of these metrics.

+## Overview

 In this guide we will configure advanced routing rules for multiple applications. These rules will showcase request matching by path, headers, query parameters, and method. For an introduction to exposing your application, we recommend that you follow the [basic guide]({{< relref "/how-to/traffic-management/routing-traffic-to-your-app.md" >}}) first.
 
 The following image shows the traffic flow that we will be creating with these rules.

 The goal is to create a set of rules that will result in client requests being sent to specific backends based on the request attributes. In this diagram, we have two versions of the `coffee` service. Traffic for v1 needs to be directed to the old application, while traffic for v2 needs to be directed towards the new application. We also have two `tea` services, one that handles GET operations and one that handles POST operations. Both the `tea` and `coffee` applications share the same Gateway.

+## Overview
+
 Securing client server communication is a crucial part of modern application architectures. One of the most important steps in this process is implementing HTTPS (HTTP over TLS/SSL) for all communications. This encrypts the data transmitted between the client and server, preventing eavesdropping and tampering. To do this, you need an SSL/TLS certificate from a trusted Certificate Authority (CA). However, issuing and managing certificates can be a complicated manual process. Luckily, there are many services and tools available to simplify and automate certificate issuance and management.

 - Use [Let’s Encrypt](https://letsencrypt.org) as the Certificate Authority (CA) issuing the TLS certificate.
 - Use [cert-manager](https://cert-manager.io) to automate the provisioning and management of the certificate.
 
-## Prerequisities
+## Before you begin
 
 - Administrator access to a Kubernetes cluster.
 - [Helm](https://helm.sh) and [kubectl](https://kubernetes.io/docs/tasks/tools/#kubectl) must be installed locally.
 - [NGINX Gateway Fabric deployed]({{< relref "/installation/" >}}) in the Kubernetes cluster.
 - A DNS-resolvable domain name is required. It must resolve to the public endpoint of the NGINX Gateway Fabric deployment, and this public endpoint must be an external IP address or alias accessible over the internet. The process here will depend on your DNS provider. This DNS name will need to be resolvable from the Let’s Encrypt servers, which may require that you wait for the record to propagate before it will work.

+Learn how to modify the response headers of your application using NGINX Gateway Fabric.
+
+## Overview
+
 [HTTP Header Modifiers](https://gateway-api.sigs.k8s.io/guides/http-header-modifier/?h=request#http-header-modifiers) can be used to add, modify or remove headers during the request-response lifecycle. The [ResponseHeaderModifier](https://gateway-api.sigs.k8s.io/guides/http-header-modifier/#http-response-header-modifier) is used to alter headers in a response to the client.
 
 In this guide we will modify the headers for HTTP responses when client requests are made. For an introduction to exposing your application, we recommend that you follow the [basic guide]({{< relref "/how-to/traffic-management/routing-traffic-to-your-app.md" >}}) first.
 
 We'll begin by configuring an app with custom headers and a straightforward HTTPRoute. We'll then observe the server response in relation to header responses. Next, we'll delve into modifying some of those headers using an HTTPRoute with filters to modify *response* headers. Our aim will be to verify whether the server responds with the modified headers.

 In this guide, we will show how to specify the TLS configuration of the connection from the Gateway to a backend pod/s via the Service API object using a [BackendTLSPolicy](https://gateway-api.sigs.k8s.io/api-types/backendtlspolicy/). This covers the use-case where the service or backend owner is doing their own TLS and NGINX Gateway Fabric needs to know how to connect to this backend pod that has its own certificate over HTTPS.

 - _Developers_ who would like to [contribute](https://github.com/nginxinc/nginx-gateway-fabric/blob/main/CONTRIBUTING.md) to the project.
 
 The reader needs to be familiar with core Kubernetes concepts, such as pods, deployments, services, and endpoints.

-## NGINX Gateway Fabric Overview
+## Overview
 
 NGINX Gateway Fabric is an open source project that provides an implementation of the [Gateway API](https://gateway-api.sigs.k8s.io/) using [NGINX](https://nginx.org/) as the data plane. The goal of this project is to implement the core Gateway APIs -- _Gateway_, _GatewayClass_, _HTTPRoute_, _GRPCRoute_, _TCPRoute_, _TLSRoute_, and _UDPRoute_ -- to configure an HTTP or TCP/UDP load balancer, reverse proxy, or API gateway for applications running on Kubernetes. NGINX Gateway Fabric supports a subset of the Gateway API.
