Center dropdown for pipeline's  mini graph

Closes #27586

See merge request !12087

We never want to skip the check, so that some actions did so was a mistake.

Older pipelines can contain jobs without a name, in which case
'nameless' is used right now, so we can properly still handle other
actions on these jobs.

Fixes gitlab-org/gitlab-ce#33403
