Fix: release workflow

[lwasser]

@Midnighter created a nice workflow that will publish to pypi on release. We now want to set things up so

1. we use pypi trusted publisher workflows
2. we separate the build and the publish into two sections of the workflow

for reference see how we are doing things for pyosmeta. once we publish to pypi we can then create a trusted workflow using that specific project on pypi.

@Revathyvenugopal162 I just merged your PR. I'm so sorry about how slow I've been responding. Would you like me to create a release, or would you like to do it?
