chore(dependencies): don't create an autobump PR for halyard on a fro…

…nt50 release branch (#1115) (#1165)

since release branches in halyard don't align with release branches in front50.  For
example, a release-1.27.x branch exists in both front50 and halyard.  In front50
release-1.27.x aligns with spinnaker version 1.27.x, but halyard version numbers are
independent from spinnaker versions.

(cherry picked from commit 7fbae17)
