Metadata: Preserve tags that are not repo topics by adding as repo topics

Expected behavior

When a user adds tags via code.json, they should be kept going forward in future code.json PRs/updates.

Actual behavior

Tags that are added via code.json will be removed in the next update-code.json PR. I believe this is due to these tags not being repository topics, thus are overriden. Alignment between tags and repo topics is needed. Maybe we can solve this by new tags being added as repo topics

Steps to reproduce the behavior

1. Add a new tag to the tags array in the code.json. This tag is not a repository topic
2. PR with new addition is approved and merged into main.
3. The next time the action is run, the new tag will be removed in the generated PR since it is overriden by repository topics.

Example shown here: https://github.com/DSACMS/gov-codejson/pull/45/files#diff-5229b349cd89869ad0b0d4411a11f45b5f4ae754ddc298f4ba7051278d11d9b3R53-R59

• I added tags in line 58-63 from a previous PR.
• This current PR removed tags in line 58-63 since they are currently not added as repository topics.
• I added "featured" tag. Next time the action is run, I suspect this will be deleted in the next PR.

Once this is fixed, update code.jsons for list of affected repositories accordingly:

• gov-codejson
• cms-gource

• INFO: I looked into the PR that was linked in the thread. The proposed solution there actually applies to a similar, but different, ticket, Metadata: Languages being overridden by GitHub API #93. Julio referenced the ticket I'm working on as an example because the two issues are related, but the discussion in that thread is not the implementation for this ticket.
• GOAL: By EOB, @isaac-rtc will have a PR attached for review: Change that fixes issue 92 #131
