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

[lemeurherve]

This change fixes the manifest by adding the missing target updating WAR_SHA value in the Dockerfiles, and by relaxing the match pattern used for golden files to also update the short tags.

It also adds skip-changelog label to the action, as bumps from this manifest are equivalent to a noop in term of content in the published image.

Amends:

• chore(updatecli): keep default JENKINS_VERSION and WAR_SHA up to date #2171
• chore(updatecli): fix default JENKINS_VERSION manifest #2200

Ref:

• Bump default JENKINS_VERSION to Weekly 2.546 #2199 (review)
• Default JENKINS_VERSION should be updated more frequently #2165

Testing done

updatecli diff --debug --clean --config ./updatecli/updatecli.d/jenkins-version.yaml --values ./updatecli/values.github-action.yaml
