Add functionality to test contrib modules

Problem/Motivation

Another use case where DrupalPod could help is to evaluate contrib modules without installing them in a local installation. It would be great if, instead of being able to open DrupalPod only to test patches/MRs, this could be used to test contrib modules releases.

Proposed resolution

It would be great if there was an option on the contrib module pages to test it, even maybe to test each branch?
