(CONT-930) - Roll out gh-changelog

[jordanbreen28]

This PR:

• Replaces pdk release prep with gh-changelog
• Generates release notes using gh-changelog get which can then be viewed on github

It's worth mentioning that for the time being there is no autoversioning, so modules will need to have a manual version value passed to the workflow run. (similar to the process already used for tooling)

I wonder if it's time to standardise workflow naming across modules now?

For example:

auto_release => release_prep

It would make more sense @chelnak, auto_release always seemed to be a weird name for it I thought 💯
