v2.1 - Alpine-based

This update switches the base Docker image to pipelinecomponents/perl-critic, which is Alpine-based and lighter/more recent than the dinosaur avastsoftware base I used before.

Have fun! 🎊

V2 now using annotations

This versions now posts violations directly using the Github check run API, instead of dropping a comment on your commit.

Thanks a lot to @hangy for implementing this.
