When the CI vars.ROLE is forgejo-coding, it is assumed to be the
repository where collaborative coding happens,
i.e. https://codeberg.org/forgejo/forgejo
When the CI vars.ROLE is forgejo-testing, it is assumed that only codebase
testing is to be run and no other tests such as release build
integration, label constraints, backporting etc.
