Fix PR commit links on submission (GitHub’s bug)

GitHub has had this really annoying bug that changes PR commit links (e.g. this one) into non-PR-related links like this: https://github.com/sindresorhus/refined-github/commit/cb44a4eb8cd5c66def3dc26dca0f386645fa29bb

This only happens to auto-linked URLS like https://...etc and not to [text](https://...etc)

We can’t fix these links after they’ve been submitted but we can do it before submission.

This feature should should:

1. Listen to comment form submissions
2. Detect plain URLs to PR commits (and skip markdown links)
3. Replace plain urls with identical markdown links, like [https://...etc](https://...etc)

Step 2 is easy to implement in most places (e.g. find a URL surrounded by spaces) but it can be tripped with content like [this url https://... is the problem](https://...) (which… probably does not happen)

This is really cool—the find of feature that makes me proud to use Refined GitHub. Nice work everyone. The styling of the warning is especially nice.
