Update extension author and repository URL

* Update plugins/inc to use transitional syntax

* Add CI job for validating plugins/inc

* ci: work around broken entrypoint in sourcemod-spcomp image

* ci: only compile Pawn plugins against master includes

* ci: restore per-version compile-plugins matrix now that spcomp images are fixed

* ci: reuse sm.branch as the image tag directly
