Troubleshooting documentation does not support known issues with WSL2

[jameswithers89]

Describe the bug

This was originally going to be a bug report titled "Editing src/App.js and saving to reload does not refresh the browser in WSL2", when I discovered during the writing of this report that inotify is not fully supported in the 9P filesystem protocol on WSL2

Which terms did you search for in User Guide?

Followed https://create-react-app.dev/docs/troubleshooting/#npm-start-doesnt-detect-changes:

• The file is imported by the entrypoint
• The project is not in a Dropbox folder
• This doesn't appear to meet the criteria of Watcher doesn't see a new file called "index.js" inside a subfolder #1164
• https://webpack.js.org/guides/development/#adjusting-your-text-editor referred to missing settings in PhpStorm, though I disabled "Back up files before saving" as the next closest option (made no difference)
• The project path does not contain parentheses
• Adding CHOKIDAR_USEPOLLING=true to .env did not work

Whilst checking watchers, as I am using WSL2 I searched online and came across https://stackoverflow.com/questions/63402588/how-can-nodemon-be-made-to-work-with-wsl-2. This solved the problem of saving files not refreshing the browser

Steps to reproduce

(Write your steps here:)

1. npx create-react-app my-app
2. cd my-app
3. npm start
4. Make changes to src/App.js
5. Follow troubleshooting guidance at https://create-react-app.dev/docs/troubleshooting/#npm-start-doesnt-detect-changes as changes are not detected

Expected behavior

The troubleshooting guidance refers to known issues with WSL2: https://stackoverflow.com/questions/63402588/how-can-nodemon-be-made-to-work-with-wsl-2

Actual behavior

The troubleshooting guidance does not refer to the known issues with WSL2
