Merge bitcoin/bitcoin#28478: ci: Temporarily disable test-each-commit

fa2cb2f Revert "Merge bitcoin/bitcoin#28279: ci: Add test-each-commit task" (MarcoFalke)

Pull request description:

  This should unbreak the GHA CI for now, and allow someone to fix the task in a follow-up. The issue is bitcoin/bitcoin#28279 (comment) .

  If no one fixes it, it can be replaced by a Cirrus CI self-hosted runner.
