Fix: scripts changelog cli per page set to 100

GitHub pagination was limiting the result to 30 issues.
This fix makes the changelog script return up to 100
issues. Will have to add a loop to fetch more once we
merge more than 100 PR's that should be added to the
changelog.

Also, fixes a bug where issues that were not included
in the milestone were being returned.
