Show a "View Branch in Editor" button for PRs

Description

Add a button to PRs that allow you to quickly open VS Code for the branch being reviewed on github.dev.

I find it useful when reviewing big PRs to take a look at a specific branch in the web editor, so I don’t have to download the branch locally.

For any given branch in a repo, you can simply open the VS Code web editor provided by GitHub with this URL structure:

https://github.dev/{username}/{repo}/tree/{branch}

Example editor on Django: https://github.dev/django/django/tree/stable/4.1.x

Example URL

https://github.com/django/django/pull/15730

I have good news! The button is already on your keyboard and you can find it by the symbol <kbd>.</kbd>; it works on any repo, folder, file or PR
