Remove supporting data releases from PyPI automate publishing

[ocefpaf]

We should not publish the supporting data on PyPI. I'll work on it ASAP, for now I removed the two published artifacts manually.

Ah, I see -- thanks for cleaning this up!

So far it seems that it was a mistake on my part somewhere. If one points the data release to the right branch that should not happen. I'll test that again soon...
