Reorganize dependencies

[lilyminium]

Changes made in this Pull Request:

• Reorganizes dependencies in setup-deps/action.yaml to move the CONDA_MIN_DEPS, CONDA_OPT_DEPS etc. into environment variables

This is just a cosmetic change and shouldn't change anything. Tests are failing because I haven't rebased yet to fix #3494.

Test run here: https://github.com/lilyminium/mdanalysis/runs/4725421554?check_suite_focus=true

Link specifically goes to a run where full dependencies are not installed; you can click on install_deps > Run # setup full variable > env to inspect CONDA_MIN_DEPS, CONDA_OPT_DEPS, and so on.
