Nibble 0.22.2

What's fixed

• A site builds its assets again. The rich text editor's character counter and placeholder, and the Control Plane's
  calendar, use packages that 0.22.0 didn't declare, so bin/vite build (and a deploy) could fail with failed to resolve import "@tiptap/extensions". Both are declared now, and a test fails when Nibble's frontend imports a
  package it doesn't declare.
