Bugfix release Lucene 10.3.1

NOTICE:

I am now preparing for a bugfix release from branch branch_10_3

Please observe the normal rules for committing to this branch:

* Before committing to the branch, reply to this thread and argue
  why the fix needs backporting and how long it will take.
* All issues accepted for backporting should be marked with 10.3.1
  in GitHub, and issues that should delay the release must be marked as
Blocker
* All patches that are intended for the branch should first be committed
  to the unstable branch, merged into the stable branch, and then into
  the current release branch.
* Only GitHub issues or pull requests with milestone 10.3.1 and
  priority "Blocker" will delay a release candidate build.

Currently the release only has the performance bug fix:

Thank y'all
