Remove unused test_suite() that now causes unittest and pytest warnings

supervisor/tests/test_confecho.py::test_suite
  /home/runner/work/supervisor/supervisor/supervisor/tests/test_confecho.py:18: DeprecationWarning: unittest.findTestCases() is deprecated and will be removed in Python 3.13. Please use unittest.TestLoader.loadTestsFromModule() instead.
    return unittest.findTestCases(sys.modules[__name__])

supervisor/tests/test_confecho.py::test_suite
  /home/runner/work/supervisor/supervisor/.tox/py311/lib/python3.11/site-packages/_pytest/python.py:199: PytestReturnNotNoneWarning: Expected None, but supervisor/tests/test_confecho.py::test_suite returned <unittest.suite.TestSuite tests=[<unittest.suite.TestSuite tests=[<supervisor.tests.test_confecho.TopLevelFunctionTests testMethod=test_main_writes_data_out_that_looks_like_a_config_file>]>]>, which will be an error in a future version of pytest.  Did you mean to use `assert` instead of `return`?
