fix: add note on keyrings and hatch

[lwasser]

In our workshop we ran into issues with publishing to PyPI using hatch because it requires a keyring to be setup and codespaces don't support that. this will impact others. for those instances we decided to use twine

We should add a small breakout with instructions if the keyring becomes problematic for users to use twine instead. The text for these instructions is in the document linked above.
