Thanks for contributing, @JarvisX-Z. I need to close this PR as issue #1308 is not assigned to you, and @Ridhi-03Kumari has already expressed interest in working on it on the issue itself. I've directed them to claim it, so it will be taken shortly.

The documentation change itself is accurate - the regex does support [bot] suffixes and your JSDoc correctly reflects that. The issue here is purely process.

A note on workflow:
I've raised the "please wait for assignment before opening a PR" concern on your previous PRs - I closed #1114 for it and left an explicit warning on #1156. I understand you're eager to contribute, and that's great! But the assignment step protects everyone: it ensures you won't put in work on something that's already being done by someone else - exactly what's happened here.

If you're looking for something to work on, check out the open unassigned issues and comment /assign on one before starting. And please feel free to reach out if you have any questions or concerns about the process - happy to help clarify so we can avoid this happening again!
