chore(updatecli): add missing target and relax match pattern in JENKINS_VERSION manifest (#2201)

* fixup: also update short tag in golden files

* add missing `updateWarShaInDockerfiles` target

* add `skip-changelog` label as this bump is equivalent to a noop with regard to the content of the image
