Python template incorrectly updated

[RyanHill-MSFT]

See MicrosoftDocs/azure-docs#122596.

If the --auth parameter is passed into func new CLI command, the AuthLevel for Python is set in CamelCase which doesn't match Azure Python SDK

I can confirm this issue with 4.0.5801:

$ func start
Found Python version 3.8.10 (python3).

and in function_app.py:

import azure.functions as func
import datetime
import json
import logging

app = func.FunctionApp()

@app.route(route="HttpExample", auth_level=func.AuthLevel.Anonymous)
def HttpExample(req: func.HttpRequest) -> func.HttpResponse:
    ...

Changing it to func.AuthLevel.ANONYMOUS lets the API run as expected.

Still an issue in 4.0.5858
