The response seems to be correct, as if we don't find the package, it should be a 404

However, if we use the correct params, we would get 200
for example:
https://test.thoth-station.ninja/api/v1/python/package/versions?name=tensorflow&os_name=ubi&os_version=8&python_version=3.6

maybe we should keep the default example pointing to ubi8 and python 3.8
till we get ingestion done for ubi9 and python3.9

changing these respectively should give default results.
