## What
We want to add Kat as a required reviewer when breaking change releases are made. This adds some logic to our existing checks to do so.
This also sets `request-reviewers: true` on our action so reviews are automatically requested when required.
Close https://github.com/airbytehq/airbyte/issues/31141
## How
- Created new group, `breaking-change-reviewers` of which Kat is the only member currently to make a bit more flexible if we do want to change who gets notified or add more people.
- Refactor mandatory reviewer logic to support multiple required review groups at a time, rather than just requesting the first group.
- Add a method to get diff from connector metadata, + refactor the current method to get acceptance test config changes to use a common method.
- Since it's not just acceptance test config changes that cause required reviewers, also moved out some code from `acceptance_test_config_checks` to `required-reviewer_checks`
