Streamline pipeline validation tasks for PG upgrade to align with standby approach
What
The MR updates PG upgrade template Quality tasks. As discussed within teams, Test Platform engineers are on standby during PG upgrade, but triggering the pipelines and checking for results - pass/fail - can be done by anyone with the team.
Why
This change allows to streamline the process further and works similarly to dev escalation - engineer is on standby and only involved when there is a failure.
