[FR] Connect to firebase storage emulator

从链接的 Firebase Emulator Suite 文档开始，尤其是 Admin SDK Storage 部分，并将其中的环境变量名称与 issue 中描述的 Python Admin SDK 行为进行比较。完成标准是文档使用 STORAGE_EMULATOR_HOST，并清楚说明如何获取模拟的 bucket；issue 还询问应在哪里提交这项文档更正。

**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.
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. 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, 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.
