Should changelog check prevent test jobs from starting?

Summary

The check for changelog entries is the last one in the CI pipeline - although it is simple check. Suggest to move it forward maybe in parallel to the linter stage? This way one does not wait a long time for the CI pipeline to finish then it fails because of a 1-line changelog missing.

Suggest also to document that the types of changelogs are fixed. In SimPipe we have e.g., a doc case. We can use for that maintenance or whatever - the issue is just that it should be documented (I had to do a long search through aiv-toolkit code to find where this is defined - as I was puzzled why the test fails - the pipline output here unfortunately collapsed the line which lists the required types)
