[CT-2345] Automate changing changelog kinds

[emmyoop]

We would like to use special kinds for projects to communicate the drive behind certain changes.

Sometimes the name of the project might change mid-project so we need to ability to update the kind and all associated changelog yamls automatically. Ideally this could be done across adapters at the same time - possibly allow an option to run for a single repo or across all repos.

Open Questions:

• How should dbt-docs be handled? Should it also get this special kind or just continue to function with the Docs kind and we have a standard to add [project name] in front of the change? dbt-docs changelogs havve a decent amount of special processing because they point to a different repo. Not a blocker, just a fact.

• Should already released betas get the kind updated in the markdown file? The associated yaml files should definitely get updated so that when the final release gets rolled up they categorized correctly. If we do change those markdown files, should we also change the release notes in GitHub?

This is a blocker to be able to have a changelog kind per project
