This updates the auto-labeler to match a specific issue title that is
going to be used for requesting commit access and then add the
infrastructure:commit-access-request label.
This will notify the admin team who will be able to handle the request.

- Only adds 'new issue' if no other label is added
(https://github.com/llvm/llvm-project/issues/65701)
- No not add labels if labels were already set
- Only add `foo` if there are no `foo:bar` label being added (although,
we don't use that yet)
Fixes#65701
