Functions Python version conflict 3.12 and 3.11

### [REQUIRED] Environment info

**firebase-tools: 13.3.0**

**Platform: macOS, Ubuntu (Github Actions)**

### [REQUIRED] Test case

Fresh Python functions project with both Python 3.11 and 3.12 installed

### [REQUIRED] Steps to reproduce

1. Start a new (or use existing) Firebase project and init Python functions
2. Install Python 3.12
3. Build the venv
4. Install pip requirements (firebase-functions, firebase-admin)
5. Build a function
6. Attempt to run the emulators and it complains that you're not using Python 3.11
```
Failed to load function definition from source: FirebaseError: Failed to find location of Firebase Functions SDK. Did you forget to run '. "/venv/bin/activate" && python3.11 -m pip install -r requirements.txt'?
```
7. Install Python 3.11
8. Build the venv using 3.11
9. Install pip requirements using 3.11
10. Emulators run
11. Attempt to deploy the functions and it complains that you're not using Python 3.12
```
Error: Failed to find location of Firebase Functions SDK. Did you forget to run '. "/venv/bin/activate" && python3.12 -m pip install -r requirements.txt'?
```

### [REQUIRED] Expected behavior

Emulators should work with Python 3.12 and deploy should work with Python 3.11 when both are installed.

### [REQUIRED] Actual behavior

Emulators fail to start the Python functions if the venv was setup using 3.12
Deploy fails when venv was setup using 3.11 if 3.12 is also installed
