ci: run Renovate from asxpi/renovate
Renovate now runs from its own repository for every repo, with the
shared rules in its preset. Extend that preset here and keep only what
is specific to this repo (the Ansible var manager, the Paper JRE, the
runner and nix notes); drop the workflow that ran it for iac alone.

# Forgejo Actions runner. It runs as a container and starts job containers
# through the Docker socket. Its registration lives in
# /opt/forgejo-runner/data/.runner and is state, not configuration.
#
# Deploying a change to it restarts the runner under the job that deploys:
# the change lands, that job shows as cancelled, and the next run confirms
# the result.
