Bump OS distro versions
Bump the OC distro version used in the tests. This not only keeps us current, but also sidesteps the failures we've seen in the debian/bullseye caused by the package-cloud bug we attempted to address here. It turns out that bug only affects bullseye, so upgrading to forky sidesteps the issue. `bullseye was old anyway...
Tested via
RUNNER_FROM_VERSION="18.5.0" RUNNER_TO_VERSION="18.6.0~pre.291.g561d06ae" RUNNER_FROM_BRANCH="gitlab-runner" RUNNER_TO_BRANCH="unstable" make deb
RUNNER_FROM_VERSION="18.5.0" RUNNER_TO_VERSION="18.6.0~pre.291.g561d06ae" RUNNER_FROM_BRANCH="gitlab-runner" RUNNER_TO_BRANCH="unstable" make rpm
You can optionally add --set "*.output=type=docker to the docker buildx bake invocation to actually create the docker image.
