Description

Adding the GitHub actions and the go script for the changelog automation.
When a PR is merged using squash and merge, the text from the body of the squash and merge is checked for a changelog entry.

It is checking for [BUG], [ENHANCEMENT], or [FEATURE]. Breaking changes need to be added to the changelog manually.
The automation will add the [GH-12345] to the end of the entry.

The automation will check if a PR is already open for the next release. If one is open, it will add the entry under the first matching header. If a PR is not already open, it will open a PR on a branch called automated-changelog, update the headers, and add the new entry. It does NOT currently add entries/sort entries in alphabetical order, that is a future enhancement.
