Tracking issue for the rest of the items we are automating in releases based on comment in #4849 :

Still missing:

• automatically determining which release scope and type is required
• actually releasing the packages once the PR is merged (currently needs to be done manually via NODE_AUTH_TOKEN=<your-token-here> npm run release:publish)
• automatically creating the releases once the PR is merged (currently needs to be done by running npm run _github:draft_release:stable, _github:draft_release:experimental, _github:draft_release:api) and then publishing the created draft release
