@nicpuppa I'm disabling the TimerTests with this PR so the ZPR release is unblocked.

UPDATE: I applied a new backport release-8.6.0-alpha5 label so the disabling is backported to the release branch.

Should we disable those test only on the release branch ? @koevskinikola

@nicpuppa that's a good point. Better to leave them visible on main so we don't delay the fix. I'll rebase this PR on the release branch.
