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

…t release branch (#946)

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