ansible: Make containers advertise "docker-noble-main" tag

This tag is used to transition containers to run Ubuntu noble.
Mind that currently, the container actually pulled will still be focal
until either DOCKER_TAG is changed to "main-noble-{arch}", or DOCKER_TAG
is overridden in the relevant `/etc/actions-runner/runner_unit-\d\d.env`
file.
