Azure API References don't offer documentation on the Python v2 classes

As described in https://github.com/Azure/azure-sdk-for-python/issues/34983 and https://github.com/Azure/azure-sdk-for-python/issues/34985 the Azure Functions SDK API Reference docs don't include documentation for the Python v2 classes such as `azure.functions.FunctionApp`, `azure.functions.Blueprint`, `azure.durable_functions.DFApp` and `azure.durable_functions.Blueprint`.

Those classes should be included in the Classes section of the package pages, along with documentation for all of the decorators.
