Handle large comparisons results from GH API to address missing authors in release workflow

The GH API returns a list that is limited to 250 commits as mentioned here

https://docs.github.com/en/rest/reference/repos#compare-two-commits But it does offer pagination to access the rest of the commits.

Explore ways how this could be used to retrieve the list of contributors between Final release tags which generally would include a large number of commits. 

This justifies the missing contributors' names from the release workflow right now (1.6.0.Final to 1.7.0.Final).

NB: The missing v1.7.0.Final tag from the docker-images repo has been added which initially caused the failure of the workflow.
