Tests fails to clean up test environment on Windows if test doesn't pass (PermissionError)

If test passes, there's no issues

py -m pytest -p no:pytest-blender tests\multilspy\test_multilspy_python.py
# tests\multilspy\test_multilspy_python.py::test_multilspy_python_black PASSED

But if test fails, it fails with the error below and folder .multispy/hash is not removed.

To make it fail, let's add exception to this part:
https://github.com/microsoft/multilspy/blob/db809145c4f516e07ef88801b5137e48430a47c5/tests/multilspy/test_multilspy_python.py#L30-L34

E.g.

        async with lsp.start_server():
            raise Exception
            result = await lsp.request_definition(str(PurePath("src/black/mode.py")), 163, 4)

Error:

tests\multilspy\test_multilspy_python.py::test_multilspy_python_black FAILED

Start with create_test_context in tests/test_utils.py and the failing test in tests/multilspy/test_multilspy_python.py. Run the provided pytest command on Windows with an exception inside lsp.start_server(). Done means the temporary .multilspy directory is removed without a PermissionError when the test fails.
