What this PR does / why we need it: Adds 'cj87holler' to maintainer allow-list in both .mergify.yml and pull_request_rules, so that approvals from thsi account satisfy the single-approval condition in the same way as existing maintainers. No rule logic is changed - this is a two-line addition to the existing author~=^(...) regexes.

Thanks @sarhiri and @dave-gantenbein for the reviews. Flagging that this is blocked by a bootstrap issue rather than anything in the diff: Mergify evaluates .mergify.yml from the base branch, so this PR can't satisfy the maintainer-author condition it's adding. The #approved-reviews-by>=2 branch also isn't met, it looks like only one of the two approvals is counting, since Mergify only counts reviewers with write access.

@mauriceyap could you add an approval? That should get to two counting approvals and turn the check green without needing an override
