JENKINS-53016 changed the automatically computed serialVersionUID for HyperlinkNote (ModelHyperlinkNote was not affected), which meant that hyperlinks in build logs created in Jenkins 2.138 or older could not be viewed correctly in Jenkins 2.139 and newer. We should restore the previous serialVersionUID so that those hyperlinks can be viewed correctly, though it will break compatibility for the builds between 2.139 and the version in which this fix is released.

There is no reason to backport this fix, because JENKINS-53016 is not included in the 2.138.x LTS release line.
