Biosimulators GitHub-Hosted Test Suite does not properly validate (VCell)

[CodeByDrescher]

##Background
We submit a containerized version of VCell to the Biosimulators site for use in projects such as Henry Jakubowski's textbook. Our submissions are validated by a Biosimulator's Test Suite before being accepted. We have a local copy of this test suite that we use to validate before officially submitting online.

##Problem
The online validation fails where the local test suite does not.

##Progress
Problem lies within the GitHub action itself, as manually entering the action with a tmate session reveals VCell is valid when manually run by a user.
