Features: CodeMirror 6

Finally CodeMirror 6 is here. The majority of work has been done by @onovy in #464.

• Migrate the editor from CodeMirror 5 to CodeMirror 6: the vendored CM5 files are replaced
  by a single bundle built from source with esbuild, all editor features (markdown formatting
  helpers, table editing, list continuation and indentation, link handling, search dialog,
  inline attachment upload and preview toggle) have been ported, and GFM support (task lists,
  strikethrough, tables) is enabled, see #464 #520
  (1c76bd9, cd08166, b8492a4, cea3dab, aa87116, 13d75bb, d1283db by @onovy).
• Add syntax highlighting for wikilinks and embeddings in the editor, see #520 (e1fbc03, 403cfce, c6011e6).
• Highlight trailing whitespace in the editor, see #520 (2d53b93).
• Use a 4-space indent unit in the editor to match the wiki's markdown conventions, see #520 (2825582).
• Enable autocorrect and autocapitalize in the editor on mobile, see #520 (f852d2d).

Bug Fixes

• Restore visual parity with the CM5 editor in both light and dark themes: nested list depth
  coloring, grey inline and fenced code, and the checkbox color, see #520
  (3b7c05f, c26a8c4, 6e8419a, 0a01cac, 28a515f, ff0d7aa, a422d02 by @onovy).
• Fix the invisible editor selection in dark mode caused by a CSS specificity issue, see #520 (8d6d144 by @onovy).
• Prevent content duplication when pasting an image in the editor, see #520 (b0a8acd).
• Preserve the cursor position when an inline attachment upload completes, see #520 (764514a).
• Fix dark mode colors of the DataTable selector dropdown, see #519 (484211a).
• Remove accidental globals in otterwiki.js (5786c57).
• Match article headings for the sidebar table of contents highlight (8629caa).
• Use per-platform pip caches in docker builds (bfc5e73).

Refactoring

• Move the frontend sources and npm tooling into frontend/, see #520 (483ccdf).

Dependencies

• Bump esbuild from 0.19.12 to 0.28.1 and rebuild the editor bundle, see #521 (33b5313 by @dependabot, 5fa9962).
