subclass of Response class should render open-api properly

[asomethings]

I'm not sure if it's a bug or intended behavior so asking a question here.

When generating openapi schema it seems like it only checks for StarliteResponse and use wrong return annotation.
I think it should use issubclass to check class instead of using is operator.

Below is a reproducible which will throw an ImproperlyConfiguredException.

from starlite import get
from starlite.response import Response as StarliteResponse

T = TypeVar("T")

class CustomResponse(StarliteResponse[T]):
    pass

@get()
def health() -> CustomResponse[str]:
    return CustomResponse('')
