pre_release_merge: allow `-release` branch testing
always_trigger_pipeline works as expected: https://gitlab.isc.org/isc-private/bind9/-/jobs/4429126
I've updated the main
, bind-9.18
and 9.18-sub
schedules as an example of how this can work.
Only downside I can think of is that we'll have to juggle with the schedule variables twice per release (if we want to have this testing, which might not always be the case), and we'll have to delete the v9.Y.Z-release-PRE-RELEASE
branches that will be left behind.
