TST: add workflow_dispatch action to test pysatNASA with latest pysat RC

[jklenzing]

Description

Addresses ROADMAP

Adds an additional workflow to download pysat from test.pypi for integration testing with future pysat releases. Workflow is manually triggered (button will appear when merged into main). Pushing this forward now since we are about to relase new code.

Type of change

• New feature (non-breaking change which adds functionality)

How Has This Been Tested?

Setting to push and inspecting the logs at https://github.com/pysat/pysatNASA/actions/runs/3346690449 to ensure that the correct things are installed.

Test Configuration

• Operating system: Mac and Windows
• Version number: Python 3.10
• Github Actions

Rationale:

• Just using "latest" python version supported. This will only run from main, so updates will be infrequent in theory. Enforcing NEP29 here will only cause more headaches.
• Testing for both ubuntu and windows
• We could add tests with the pysatCDF RC as well. This could either be in a single workflow (easier to maintain, more jobs to run each time) or as two separate workflows.

@aburrell? @rstoneback? Thoughts?

[jklenzing]

Having had a little more time to think about, I'm inclined to leave pysatCDF RC testing out for the time being. The no-binary option complicates things.

[jklenzing]

Added mac tests for both workflows. Needed a gfortran reinstall to get pysatCDF to work.

[jklenzing]

Still need a review here before the RC is finalized
