Add cj87holler to Mergify maintainer lists

[cj87holler]

What type of PR is this? Chore - repository configuration

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.

Greptile Summary

This repository-configuration change adds cj87holler to both Mergify maintainer allow-lists, allowing pull requests authored by that account to satisfy the maintainer one-approval condition.

• Updates both relevant anchored author regexes.
• Does not alter the surrounding approval-rule logic.

Confidence Score: 5/5

The PR appears safe to merge because the intended maintainer account is added consistently to both applicable Mergify rules.

The change is limited to adding one account to two existing allow-lists, and no concrete defect or unintended rule behavior was identified.

Important Files Changed

Filename	Overview
.mergify.yml	Adds the new maintainer account consistently to both one-approval author allow-lists without changing rule structure.

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
