PZ-2089 - link the pr to solved jira

[bas-info-nl]

Create new actions pipeline; add-jira-link-pr-open.yml, that will add a link in Jira back to the PR that this is triggered on.

Add some sample .secrets-sample and a sample pull-request-event.json for testing the pipeline code. And mention this in the relevant README.md.

Nice. But why would we want this? It does add quite some complexity and therefore potential maintenance (if it ever breaks down, does not work correctly etc).

Personally, but maybe that's just me, I never understood why you would want to link back from an issue management system like JIRA back to Git.. ;-)

[edgarvonk]

Don't get me wrong: it's an impressive piece of code. :-) I just don't see the benefit personally.

And I'm a bit surprised that there isn't already a GitHub out there that does this? If there isn't, maybe consider making this code into an open source GitHub Action project, instead of embedding it into this project?
