qa-tests: fix workflows for release 2.60 (#10217)

Running a test every day doesn't make sense on an inactive branch. 
It also seems that the schedule trigger favours the main branch if the
test workflow has the same name on the main and other branches.
So this PR changes the test trigger to "push events".
