Docs have been moved since the tool was written so that exclusion is no
longer needed. Since the defaults were added the `pipeline` group has
expanded to include all `.github`, which we don't want to always
backport. It seems unlike that `pipeline` tooling changes are likely to
be required often on inactive branches so we'll exclude all together for
now.
