fix: use GitHub API link for juggler (handles slash branch names)

assigned to @wdconinc

enabled an automatic merge when the pipeline for 60320c8c succeeds

aborted the automatic merge because target branch was updated

Would that break if github doesn't get mirrored in time?

The mirroring should be fast enough, since

• the trigger for the eic_container build is downstream of the local build here
• the eic_container job that does the pulling of the link is a few minutes into that pipeline
• we want to move to github as primary anyway, so at some point soon this will all be starting off on github and not eicweb.
