Proposed change

Let's fix some pytest warnings!

 tests/test_core.py::test_serviceregistry_async_service_raise_exception
   /home/runner/work/ha-core/ha-core/tests/test_core.py:1250:
       RuntimeWarning: coroutine 'ServiceRegistry.async_call' was never awaited
   Coroutine created at (most recent call last)
     ...
     File "/opt/hostedtoolcache/Python/3.11.4/x64/lib/python3.11/asyncio/events.py", line 80, in _run
       self._context.run(self._callback, *self._args)
     File "/home/runner/work/ha-core/ha-core/tests/test_core.py", line 1250, in test_serviceregistry_async_service_raise_exception
       hass.services.async_call("test_domain", "REGISTER_CALLS", blocking=False)
     hass.services.async_call("test_domain", "REGISTER_CALLS", blocking=False)

 tests/test_core.py::test_serviceregistry_callback_service_raise_exception
   /home/runner/work/ha-core/ha-core/tests/test_core.py:1270:
       RuntimeWarning: coroutine 'ServiceRegistry.async_call' was never awaited
   Coroutine created at (most recent call last)
     ...
     File "/opt/hostedtoolcache/Python/3.11.4/x64/lib/python3.11/asyncio/events.py", line 80, in _run
       self._context.run(self._callback, *self._args)
     File "/home/runner/work/ha-core/ha-core/tests/test_core.py", line 1270, in test_serviceregistry_callback_service_raise_exception
       hass.services.async_call("test_domain", "REGISTER_CALLS", blocking=False)
     hass.services.async_call("test_domain", "REGISTER_CALLS", blocking=False)

Add missing await for hass.service.async_call(...).
