When CI fails to publish, the user should know

[thorwhalen]

I couldn't see the project being published to pypi, though CI should all green.

If CI doesn't publish my project, I should know.

Here, there was some silent:

WARNING  Skipping graze-0.1.9-py3-none-any.whl because it appears to already    
         exist                                                                  
WARNING  Skipping graze-0.1.9.tar.gz because it appears to already exist        

in the logs.

How do we make it fail when this happens?

See the twine command in isee.actions.

Apparently it's returning a 0 status in all cases, so github actions doesn't know something failed.

Two ideas of solution:

• pipe the twine output into something that will analyze it and decide whether to fail or not
• wait and check on the publication on pypi
