Sphinx-tojupyter

This is a major version update as it is not compatible with `myst-nb<0.14` given the way `notebook mime type overrides is specified.

There are however no **new features** and is a compatibility update to enable compatibility with latest `jupyter-book` and `myst_nb>=0.14` which is now a specified dependency.

This `minor` release includes a bug fix to improve compatibility with `sphinx-exercise`. When `titles` for `exercise` nodes are parsed (if those `exercises` are labelled then sphinx uses `numref` to resolve the numbers during the `translation` phase. Therefore this release includes a `visit_exercise_enumerable_node` method to resolve these titles.

This release brings compatibility with `sphinx>=4,5`

If you need compatibility with `sphinx<=4` please use `sphinx-tojupyter==0.1.2`

This release includes:

1. incorporates chapter context when numbering equations when using `sphinx-multitoc-numbering` https://github.com/QuantEcon/sphinx-tojupyter/pull/30

This is a minor release that incorporates some bug fixes.

. Fixes issue when building markdown tables and table_width was passed with type float (27)

This is the initial release. It is a port from [sphinxcontrib-jupyter](https://github.com/quantecon/sphinxcontrib-jupyter) which will be reworked overtime to become a specialised writer of `ipynb` files for Sphinx and is compatible with `jupyter-book` / `myst_nb`. Features such as `site` and `pdf` writers will be removed in future releases but will remain avaiable via [sphinxcontrib-jupyter](https://github.com/quantecon/sphinxcontrib-jupyter)
