[Desktop] some GitHub URLs missing from exclusion list

[LaurenWags]

Description

While testing #11463 I found that some GH URLs are missing from the exclusion list (found here: https://github.com/brave/brave-site-specific-scripts/blob/master/scripts/brave_rewards/publisher/github/utils.ts#L57-L76)

If you visit one of these pages and open the panel, you see the summary view, not the publisher view. These excluded pages should show github.com as the publisher.

Steps to Reproduce

1. Have rewards enabled
2. Navigate to a page like:
   GitHub.com/features/code-review
   github.com/security
   github.com/collections
3. Open panel

Actual result:

Expected result:

Panel should show github.com:

as it does for sites on this list:

Will assign a P5 for now since Github is currently disabled for Creators in any case.

This seems to be working correctly, pelase reopen though if I'm missing something.
