Firebase Functions for Python tries to deploy python311 even though I'm using python310

Firebase CLI isn't considering `python --version` to inform rather than just assume latest.

Instead, I get cryptic errors like this:

```
functions: Failed to load function definition from source: FirebaseError: Failed to find location of Firebase Functions SDK. Did you forget to run '. "/Users/jamesdaniels/Code/my-flask-app/.firebase/yarg-asdfierjoieroi/functions/venv/bin/activate" && python3.11 -m pip install -r requirements.txt'?
```

Would be more helpful if CLI printed something like:

```
We expected python 3.11, found 3.10.
```

in addition to the above CTA.
