Subject: [PATCH] fix: add missing @InternalExtensionOnly annotation to
 com.google.cloud.firestore.Firestore (#141)

"Client" interfaces make guarantees around compatibility for users
direct usage, however no guarantee is made for anyone implementing
the "client" interface themselves. This change adds the annotation
intended to convey this guarantee at the code level and in javadocs
that should have been here all along.
