Functions defined with `@functions_framework.http` or `@functions_framework.typed` do not support type hints

[DevJake]

Simply put, defining a function with the @functions_framework.http decorator does not support type hints. With some digging, I stumbled upon the possibility of using @functions_framework.typed, but even this does not work, nor is it documented anywhere. Please see:

1. feat: Support strongly typed functions signature #208
2. Document functions_framework.typed #290

This is taken from my attempts to create and deploy a function running python version 3.12.x. There are no error messages indicating that the cause is the type hints, only that the function failed to be ready and accepting of traffic.

I would suggest the following:

1. Type hints be properly supported for Python functions running any compatible version, given they are now standard practice for developers
2. Versions that use type hinting when they shouldn't -- or otherwise cannot be built -- show an appropriate and relevant error message

As for an example, even the most basic functions such as the following will break:

from flask import Request

@functions_framework.http
def main(request: Request):
	pass

from flask import Request

@functions_framework.typed
def main(request: Request):
	pass

Google has some of the most talented developers and extremely deep pockets and yet somehow this was overlooked. It is not a good look.
