Describe your changes

This is a shell script that installs the Netbird applications (CLI and UI) on a Linux or macOS system.

The shell script is designed to work with various Linux operating systems, including but not limited to Ubuntu, Fedora, Debian, CentOS, Raspberry Pi OS, Arch Linux, Alpine Linux, etc. The supported architectures include amd64, arm64, and 386. It can also be used on Mac OS, both on Intel and Apple Silicon architectures.

Features

• Detects for officially supported package managers (apt, dnf, yum, brew) and installs via the respective package manager.
• Installs appropriate binaries based on the system's architecture and operating system type if package manager is not supported.
• Skip netbird-ui installation for Linux systems that lack a desktop environment or for systems that have an unsupported architecture.

For testing
curl -fsSL https://raw.githubusercontent.com/bcmmbaga/netbird/main/release_files/install.sh | sh

Great job, @bcmmbaga! Could you please drop a simple description of the main features/functionality of the script? Maybe also mentioing the OS it supports, etc.

Danke!

@bcmmbaga thanks for the PR. I've left some notes that might be helpful to avoid some issues with the script. The new domain is new and we didn't have a chance to update our docs, but they are working.
