Update packaging and docker related workflows

[jenhagg]

Purpose

Add the necessary bits to publish to PyPI and remove soon to be obsolete docker build.

What the code is doing

A few things are combined here for continuity:

• new workflow to build and publish package to PyPI on new tags
• remove docker build which is moved to plug, pending Move docker build to plug repo plug#25
• specify the version of powersimdata to be installed from PyPI

For context, once we restrict the powersimdata version, the docker build as-is will no longer make sense - the image is inheriting from powersimdata:latest but then we will override that with whatever version matches the specifier.

Testing

Built the package locally, but mostly this is copy-paste from elsewhere.

Time estimate

15 min

We will publish PreREISE and PostREISE on PyPi too? I mean, in addition to PowerSimData.

[jenhagg]

Support for building a "stable" docker image based on the latest published version of postreise is included in this draft PR Breakthrough-Energy/plug#29

LGTM. We might want to update the PowerSimData version after it is released to 0.4.4

Still looks good
