* Add `act` to image to allow for GitHub workflow runs even though we are not on GitHub :-] ([d383701](https://git.griefed.de/prosper/gitlab-ci-cd/commit/d38370121b0614668f9cee0a2a966ae510a1ab89))
act requires a `.actrc`-file to be present in the executing users home directory, so `~/.actrc`. For information about the contents and configuration of this file, see [nektos/act#first-run](https://github.com/nektos/act#first-act-run) and [nektos/act#configuration](https://github.com/nektos/act#configuration)
