pack: v0.27.0 — Create QoL + aesthetic batch

Three small Create addons, no overlap with current 18-mod Create stack:

  + kubejs-create v2101.3.1-build.18
      Recipe builders for KubeJS scripts. Will replace the raw
      Create:pressing JSON in supplementaries_bridges.js with a
      cleaner event.recipes.create.* call.

  + create-encased v1.8.1-ht1
      Encased/cased variants of Create kinetic blocks (shafts,
      gearboxes, cogwheels in compact casings) for cleaner builds.

  + bellsandwhistles v0.4.7-1.21.1
      Train whistles, bells, signal lights, station decoration.

All three already deployed live; pack-version.json bumped, MC
server restarted to sync. No mod-load errors.
