Change event triggers from un/published to pre/released

[mmerklinger]

This PR changes the event triggers of the CD pipelines to respond to prereleased and released, instead of published and unpublished. There is an exception for the Pypi pipeline to only get triggered on released event. Reason for this is to not push test releases to Pypi, which could end up in a production environment.

Changes

• CD pipeline for Windows/Linux is triggered for prereleased and released events.
• CD pipeline for Pypi is only triggered for released event.
