MAINT: GA updates

[jklenzing]

Description

Addresses pysat/pysat#1051. Because pip now builds a wheel locally (by default), it tries to download setuptools from test pypi, which isn't there.

Updates RC install options for work with pysat release candidates on test.pypi

Adds a new workflow to test install of the pysatMadrigal RC from test.pypi
