CI workflow to check test / installation
This is adding some workflow to confirm we can
install the distributions on different versions of Perl.
Skip the test t/pod-files-presence.t when AUTHOR_TESTING
is not set as this requires to run make docs then rerun
perl Makefile.PL... which is not the regular workflow
