feat(rc): add complete release candidate workflow

[kylemellander]

There are now many steps to creating a release candidate and there were issues getting everything to play nice with each other. There were a lot of inferred properties that would not work in some conditions.

This PR moves the publish command from shared-workflows and allows it to be more flexible.

Then it uses that workflow to create a complete workflow that:

• creates a new RC prerelease
• Publishes that release
• Pushes the release to staging for all apps that consume the app.
