feat: updated dev tools, fix: non-breaking requests version

[jacobdadams]

The main purpose is to pin the requests version to an older package that is compatible with arcgis.

I took the opportunity to update the dev tools/actions to match the latest patterns.

this looks great. Let's get the ci stuff aligned with our best practices and then i'm excited to test the setuptools deploy. Will we need to get pypi ready for the new package name prior to a release being pushed?

I did some work on the actions stuff for this. @steveoh Would you mind taking another look? I'm also not clear on how the publish will go with the new package name. Do I need to do anything on the pypi end before it's published?

looks great.
