bindings: python tests skipping

[Justin-Xiang]

I found the test instructions in Python and CONTRIBUTING not working.

when running OPENDAL_MEMORY_TEST=on pytest on my machine, all tests will skip due to this:

@pytest.fixture()
def service_name():
    service_name = os.environ.get("OPENDAL_TEST")
    if service_name is None:
        pytest.skip("OPENDAL_TEST not set")
    return service_name

Instead, one way to run all tests is:
OPENDAL_TEST=fs opendal_fs_root=/tmp pytest -vk test
fs can change to memory or others

You are right. We recently updated our testing framework and have not updated the documentation. Would you like to submit a PR to update it?

[Justin-Xiang]

Sure, I'd like to make a PR for that, also, I found a lot of Bindings Python CI here skipped, is it expected or due to the issue above?
