Support independent releases

[carlgieringer]

Github's default release workflows seem targeted to a repo that releases a single linear artifact. But since our monorepo releases the following:

• API
• web app
• iOS app
• Chrome extension
• some lambdas
• and possible more (Android app, FF extension, additional lambdas)

We want to support the following:

• Have Github recognize the release of independent artifacts, but not consider them part of the same linear history.
• Allow users to see the history of the release of just one artifact
• Allow users to see the most recent release of each artifact
• Automate artifact-specific release notes (if possible.)
