[Misc] Drop the plugin version bump

* Five manifests carry one version, so every concurrent pull request conflicted with every other one
  on those same five lines, over something that was never part of either change. The release is now
  cut on master after the merge by scripts/release.mjs, and scripts/validate.mjs fails a branch that
  touches a version field.
