This one synchronizes "pull_request_target" workflow changes with tip of the providers-fab/v1-5 branch

[potiuk]

Same story as for v2-10-test -> that providers-fab/v1-5 branch also still has pull-request-target workflow and it needs to be removed.

[jscheffl]

Same as previous PR - but hoping that not (many/any) patch cycles on this branch are needed.

Yeah. That one should be WAY easier to get green.

We might need to do it (because of security) - and I know of some security fixes that are coming to FAB.
I prefer to do it now - when I know exactly how to fix issues, because I've just done it for v2-10-test - rather than trying to remember it 3 weeks from now.
