gcloud command to create Firestore database is incorrect

In the latest version of gcloud the command to create a Firestore database now uses --location instead of --region

It is also worth noting that the default database created, is in Datastore Mode resulting in errors like.

Error: 9 FAILED_PRECONDITION: The Cloud Firestore API is not available for Firestore in Datastore Mode database projects/<redacted>/databases/(default).
