cpanminus is broadly compatible with our syntax use of cpan, but can offer additional benefits such as
Pkg::Name@Version
definitions, as well as built-in modules to reduce the environment requirements on the system when resolving dependencies.This PR updates the perl dependency resolver to use
cpanm
if available in the environment. Tests have been updated to ensure operation with either utility, and the Github Actions workflow updated to make the utility available on Ubuntu runners (being already provided in the Windows Perl distribution).
