remove license files that are no longer part of the dependency tree

[epugh]

This is a follow up to the #3122 ticket. We need to see if Solrbot is also checking/fixing licenses.

These licenses exist on main and branch_10x and need to be removed.

Pull request overview

Removes stale third-party LICENSE/NOTICE text files under solr/licenses/ that no longer correspond to any dependency artifacts validated by Solr’s Gradle dependency/license checks (follow-up cleanup after prior dependency tree changes).

Changes:

• Delete unused license/notice files for dependencies no longer present (e.g., Micrometer core, JAXB-related, Jakarta EE artifacts).
• Remove leftover public-domain notice/license files (HdrHistogram/LatencyUtils) that are no longer referenced.
• Clean up other dangling license texts (e.g., txw2, istack-commons-runtime, Angus).

Don’t need approval to do small fixes like this. Wonder why precommit didn’t fail on the s3 PR though…

thanks.. mostly wanted another set of eyes cause I havne't done a lot in the license and upgrade side of things... I was actually shocked by this, and thought "eric, what did you do wrong" ;-). Even re-cloned my solr repo jsut to make sure I had a fresh code base!

@epugh was the problem detected by precommit or "just" log/warning output? I recall the latter. Nonetheless, looks like the bot should be updated.

It was precommit. And it may be that the bot can't identify the changes to licenses that are needed? This is an area I'm really just learning aobut!

The bot won't add LICENSE/NOTICE files, it will re-build sha1 checksum files and delete old/stale.

I think this lie https://github.com/apache/solr/blob/main/.github/renovate.json#L16 may limit the postUpgrade commands to only commit changes to sha1 and lock files, not LICENSE or NOTICE files, so probably fixed by adding a third regex to that line.
