Add typos - Source code spell checker (bevyengine#12036)

# Objective

- Avoid misspellings throughout the codebase by using
[`typos`](https://github.com/crate-ci/typos) in CI

Inspired by gfx-rs/wgpu#5191

Typos is a minimal code speller written in rust that finds and corrects
spelling mistakes among source code.
 - Fast enough to run on monorepos
 - Low false positives so you can run on PRs


## Solution

- Use
[typos-action](https://github.com/marketplace/actions/typos-action) in
CI
- Add how to use typos in the Contribution Guide

     * `cargo run -p ci -- doc` - to run doc tests and doc checks.
     * `cargo run -p ci -- compile` - to check that everything that must compile still does (examples and benches), and that some that shouldn't still don't ([`crates/bevy_ecs_compile_fail_tests`](./crates/bevy_ecs_compile_fail_tests)).
     * to get more information on commands available and what is run, check the [tools/ci crate](./tools/ci).

 4. When working with Markdown (`.md`) files, Bevy's CI will check markdown files (like this one) using [markdownlint](https://github.com/DavidAnson/markdownlint).
 To locally lint your files using the same workflow as our CI:
    1. Install [markdownlint-cli](https://github.com/igorshubovych/markdownlint-cli).
    2. Run `markdownlint -f -c .github/linters/.markdown-lint.yml .` in the root directory of the Bevy project.
-
 5. When working with Toml (`.toml`) files, Bevy's CI will check toml files using [taplo](https://taplo.tamasfe.dev/): `taplo fmt --check --diff`
    1. If you use VSCode, install [Even better toml](https://marketplace.visualstudio.com/items?itemName=tamasfe.even-better-toml) and format your files.
    2. If you want to use the cli tool, install [taplo-cli](https://taplo.tamasfe.dev/cli/installation/cargo.html) and run `taplo fmt --check --diff` to check for the formatting. Fix any issues by running `taplo fmt` in the root directory of the Bevy project.
