If available, provide a link back to Gerrit on the overview page of a build. Uses the default style (i.e. style unset), which makes it non-intrusive visually.

 | |
| # If something fails during the creation of the pipeline, the fallback

| # is executed instead which will simply report an error to Gerrit.
