Make CI run on famedly runners

By default, jobs without tags only run on CI runners configured to do so [1].
Conduit can use famedly runners, which are more powerfull than gitlab's runners, but require a tag on the job to run it there.
This commit tags each job with the "docker" tag.
On the famedly/conduit repo this means faster CI.
On other gitlab.com forks the normal ci.
Selfhosted gitlab's might need to add a "docker" tag to their runner.
