Updated dependencies after asgiref v3.9. (#2168)

* Updated asgiref dependency to v3.9

ApplicationCommunicator testing utility will now return result if
application is finished when sending input. Assert CancelledError
rather than allowing timeout.

* Dropped support for EOL Python and Django versions.
