[FR] Connect to firebase storage emulator

\*\***EDIT:**\*\*
I just discovered that it's a bug in the documentation. It is possible to connect to firebase storage emulator using the python admin sdk, but you need to set the `STORAGE_EMULATOR_HOST` environment variable instead of the `FIREBASE_STORAGE_EMULATOR_HOST` as described by the docs.
See this [answer](https://stackoverflow.com/a/75894891/17581223).
Should I close this and submit an issue somewhere else? In that case where do I need to open such issue?

**Is your feature request related to a problem? Please describe.**
I have a problem described by this [question](https://stackoverflow.com/questions/75420029/connnect-firebase-admin-storage-to-firebbase-emulator-in-python/75894891#comment133884767_75894891). But to summarize I am using firebase storage admin with python and I want to connect it to a firebase emulator running on localhost. I followed the docs [here](https://firebase.google.com/docs/emulator-suite/connect_storage#admin_sdks), added the environment variable, but now I need to get the bucket.

`bucket = storage.bucket("What do I put here?")`
If I don't put anything it gives an error, if I put a real bucket it uses that and I even tried localhost ("127.0.0.1:9199") as bucket name and it couldn't find it because it was searching for a real bucket.

**Describe the solution you'd like**
I'd like a way to get a emulated storage bucket. I think that if the environment variable is set `storage.bucket()` should return that.

**Describe alternatives you've considered**
Any other way it would be possible to use firebase storage admin with the emulator suite would be appreciated.

**Additional context**
As far as I know there is no solution for the problem described above. I don't know if this is a bug or if I'm just being dumb, so I would appreciate if you could point me in the right direction if this is not the right place.
