Sync translation infrastructure from foreman_plugin_template (#11193)

This copies the Makefile from foreman_plugin_template to resolve an
issue with the time stamp handling and pulling in new translations that
made it past 50%.

It also ignores action_names.rb since that's now considered a best
practice. Generated files do not belong in git.
