Update git submodules

* Update placement from branch 'master'
  - Merge "Add train-prelude release note"
  - Add train-prelude release note
    
    This is essentially a duplicate of the cycle highlights provided
    with the release, plus a warning about needing to upgrade to extracted
    placement in stein before the train upgrade.
    
    Few links are provided because the rest of the release notes are very
    short and will be presented adjacent to the prelude, and they have
    links.
