ci: Add Manual Release Workflow

[BrandonStalnaker]

Background

• We no longer want to use semantic-release in our release process. This workflow allows us to set the release version manually and follow our branch protection rules by creating a release branch, doing the necessary changes for each release, and then creating a PR.

It's probably worth pausing this and aligning across more of our repositories and systems unless you're seeing this as a temporary bandaid?

@jamesnrokt It certainly is a short term fix for our current release woes but in general I think it's a good path forward for us in that everything is gated behind a pull request which follows the new branch protection rules. We aren't allowed access to the keys that would allow us to upload the frameworks manually (I can send you the gChat link confirming this if you'd like) so this is kinda the only way forward with our other restraints.
