Automatically deploy Firestore rules from git

[Supereg]

Problem

We configure the Firestore rules within the repository (see firestore.rules file). Currently, this is automatically picked up by the emulator but is not deployed to Firebase itself.

Solution

Use a GitHub Action on a successful PR merge to deploy updated Firestore rules automatically to the cloud. The general Firestore rules documentation page might be helpful. To integrate it into GitHub Actions, we might want to rely on the GitHub Action for Firebase.

Additional context

We might want to consider a future setup, where we have multiple Firestore projects running (e.g. production vs. development).
Further, we should consider referencing the above documentation links in the Template Application.

We might want to look into StanfordBDHG/.github#39

@Supereg The changes in StanfordSpezi/SpeziTemplateApplication#54 should showcase all that needs to be done to set this up for our project here.

Happy to setup everything around the services account and surrounding infrastructure 👍
