Renamed the examples in docs_src from test_me.py to example.py and referenced in tests folder

But why we are running the same test twice for now?

My mistake, referenced the wrong one in one of the tests

One test is for the example where we use the general publish of the FastStream and another is when we first create a publisher object and then use its publish method

Fixed it :)
