Bug 1907217: remove * branch from RelEng github repositories and try r?#releng-reviewers!

Stage one of the plan written out in the bug.

This _should_ be quite safe. For Maple, all of the scopes that `branch:*` has are already granted by `branch:default`.

For GitHub we have some differences, but as far as I can tell, only where the explicit branches have more scopes than `branch:*` due to grants such as https://github.com/mozilla-releng/fxci-config/blob/944ea85da779ab430e932f9829f1f02bb11ee11c/grants.yml#L1185-L1200.
