chore(builder): install CodeMirror deps for the upcoming code-editor feature

Adds @codemirror/state, view, commands, autocomplete, language,
lang-html, lang-javascript, lang-css, and theme-one-dark to package.json
now (unused for now, tree-shaken out of the build) so the code-editor
feature branch doesn't need to touch package.json/package-lock.json itself
and conflict with other enh-batch branches doing the same.
