CI command continues to be broken

[carueda]

As seen below (against latest commit in master at the moment, but similarly for other branches), the unit testing trivially passes because the given run command:

        run:
          export POETRY_PYPAM_TEST_NO_PLOTS=make test          
          PYPAM_TEST_NO_PLOTS= make test

becomes a simple line:

export POETRY_PYPAM_TEST_NO_PLOTS=make test PYPAM_TEST_NO_PLOTS= make test

A possible fix:

        run: |
          export POETRY_PYPAM_TEST_NO_PLOTS=make test          
          PYPAM_TEST_NO_PLOTS= make test
