Support Jupyter YDoc v4

Widen the @jupyter/ydoc (npm) and jupyter_ydoc (Python) dependency ranges
to accept v4 alongside v3, so the extension works on JupyterLab 4.6+, which
ships @jupyter/ydoc v4 as its shared singleton.

- package.json: @jupyter/ydoc "^2.1.3 || ^3.0.0" -> "^3.0.0 || ^4.0.0"
- package.json: pin @jupyter/ydoc to ^4.0.0 in resolutions so the dev/CI
  build dedupes to a single v4 copy (transitive @jupyterlab/* still declare
  ^3); ydoc is a webpack singleton at runtime so this is build-time only.
- pyproject.toml: jupyter_ydoc ">=3.0.0,<4.0.0" -> ">=3.0.0,<5.0.0"

Also removes the temporary 'jupyterlab<4.6' CI ceilings added to unblock
main, restoring 'jupyterlab>=4.0.0,<5' now that JSD supports ydoc v4.

Closes #262
