We now set the Firebase deploy target for AIO preview deployment
via GitHub actions. It looks like configuring the deploy target
also requires authentication / or a project.

Checks out the Firebase project before setting the AIO preview targets.
Surprisingly Firebase requires a project when setting resource
identifiers for the targets. This is already done by the Firebase
deploy action from @FirebaseExtended, but we need to do it earlier.

For the deploy job we still need to use the Firebase CLI to configure
the proper hosting deploy targets. See:
011ef66a04.
We don't have node modules installed in this job, and it would
also be overkill to install them for just using firebase here.
Since the action uses `npx firebase-tools` down the line anyway,
we can use it without any speed downsides.

The AIO firebase project specifies `aio` as deploy target. This means
that we need to configure this target before being able to deploy AIO
previews.
We use the default project target as target since the preview Firebase
project does not use multi site targets. See:
