fix: trigger publish only on release

[lwasser]

closes #127

Fixes:

• sphinx design and other extensions not installing properly
• Updates docs to fix a few bugs with build (Related to deps)
• use autoapi in docs vs autodoc for simpler config
• Merge the release workflow so build and release happen in one place with different triggers.
• A few typos and bugs throughout

I hadn't noticed it was actually trying to publish on every commit - so i fixed that

[lwasser]

I had fixed the documents and somehow not committed the changes. So this fixes those bugs and issues, so the docs build with clean and simple api docs (using autoapi for simplicity).m

[lwasser]

Autoapi magically creates documentation. It' just a really nice, easy starting place. and we can redirect people to autodoc if they want more custom builds -- maybe the scientific Python guide covers that?
