Add Firebase AI to recipe version generation

[daymxn]

Per b/416734504,

This updates the GenerateTutorialBundleTask that we use to generate the tutorial bundle versions (recipe versions) to support firebase-ai. More specifically, it replaces the existing firebase-vertexai entry in the process.

While this PR removes firebase-vertexai from the tutorial bundle, it does not remove it from the BoM. That will be a breaking change we'll make down the road.
