[JENKINS-53729] - Restore computed serialVersionUID for HyperlinkNote

[dwnusbaum]

See JENKINS-53729 and #3580 (comment).

#3580 changed the computed serialVersionUID for HyperlinkNote, which caused errors in new versions of Jenkins when viewing build logs from HyperlinkNotes serialized by older versions of Jenkins.

I am happy to try to create a regression test if desired.

Proposed changelog entries

• Bug: Hyperlinks in build logs for builds run using Jenkins 2.138 or older were not displayed correctly in newer versions of Jenkins.

Submitter checklist

• JIRA issue is well described
• Changelog entry appropriate for the audience affected by the change (users or developer, depending on the change). Examples
  * Use the Internal: prefix if the change has no user-visible impact (API, test frameworks, etc.)
• Appropriate autotests or explanation to why this change has no tests
• For dependency updates: links to external changelogs and, if possible, full diffs

UpdateCenter2Test broken I guess due to upstream errors, bleh.

I checked interactively that this patch works.

Will this fix result in 2.139+ created hyperlinks not being displayed?

[dwnusbaum]

@daniel-beck Yes, we can either have compatibility with 2.138- or 2.139+ hyperlinks. If you think it would make more sense, we could add the computed serialVersionUID from 2.139 instead.

[daniel-beck]

A bit unfortunate, but we should prefer 2.138 and earlier. For one thing, that's all LTS releases, and additionally, if build logs of the last two weeks constitute a huge part of all your build logs you're churning so fast that this won't matter in two weeks.

At least that let's us write an appropriate changelog.

Pick your poison, but I agree with @daniel-beck
