Instead of hardcoding "forgejo" as the base for the daemon to store
the PID and the logs, use the base of the WORK_PATH so that a given
work path can run a dedicated forgejo instance by the same name.
* replace the high level test running actions tests with end-to-end.sh
* set DOMAIN to the IP instead of 127.0.0.1 for runner <-> forgejo communications
* move forgejo_cli from a function to a file so that it can be used by forgejo-runner.sh
* keep the documentation updates workflows separate because they need to open one PR per version
