[BUG] Async authentication doesn't play well with sync views

[selcuk]

Describe the bug
Django Ninja supports both sync and async authentication classes, but even though sync authentication works well with both sync and async views; async authentication requires async views.

To reproduce:

class MyAsyncTokenAuth(HttpAuthBase):
    openapi_scheme: str = "bearer"
    header: str = "Authorization"

    async def __call__(self, request: HttpRequest) -> Optional[Any]:
        # ...
        return {"user": "foobar"}

then

api = NinjaAPI(title="MyAPI", auth=MyAsyncTokenAuth())

this works well here:

async def my_async_view(request):
    if request.auth["user"] == "foobar":
        # The user is authenticated

but it fails with a sync view:

def my_async_view(request):
    if request.auth["user"] == "foobar":

Exception:

builtins.TypeError: 'coroutine' object is not subscriptable

Cause
Although AsyncOperation._run_authentication checks if the __call__ method of the authentication class is async, its sync counterpart (Operation._run_authentication) does not perform this check.

Versions (please complete the following information):

• Python version: [e.g. 3.11]
• Django version: [e.g. 4.2.4]
• Django-Ninja version: [e.g. 0.22.2]
• Pydantic version: [e.g. 1.10.7]

Hmm, on a closer look, this looks like a Duplicate of #756 and seems to be fixed in the latest master branch. 🎉
