Skip tests on backported docs branches.

Example backport to which this should apply: #13610

Should these edits be in https://github.com/hashicorp/vault/blob/main/.circleci/config/workflows/ci.yml instead? There's a comment at the top of .circleci/config.yml saying that it's autogenerated and not to edit it manually, and there's a section in the ci.yml file like:

  - test-go-race:
      requires:
        - pre-flight-checks
      filters:
        branches:
          # UI and Docs-only branches should skip go tests
          ignore:
            - /^docs\/.*/
            - /^ui\/.*/

Nope, I'm pretty sure that's left over from a previous attempt. That approach doesn't work for required checks like test-go, because then GH never sees the check as completed and the PR is unmergeable. I've removed these to reduce confusion.

Great, thanks for cleaning up the old stuff too!
