Add TeachBooks-Questions to the book TOC and TeachBooks Favourites list, and include Sphinx Gated Directives and TeachBooks Zoomies in the favourites page. Also tidy requirements.txt by removing an inline bump comment from the TeachBooks-Favourites git dependency. Changes touch book/_toc.yml, book/features/favourites.md, and requirements.txt to surface the new/manual links and clean up metadata.
Deleted instructie.ipynb, instructie_2.ipynb, and lesoefeningen.ipynb from the book. Updated _toc.yml to remove references to these files and moved the Sphinx-Gated-Directives manual link to the correct section. Minor update to intro.md.
Added an external manual link to the table of contents. Updated requirements to use TeachBooks from the 'issue-127' branch and adjusted comments for clarity.
Integrated the sphinx-github-alerts extension into the Sphinx configuration, requirements, and documentation table of contents to enable GitHub alerts functionality.
Added new pages for Sphinx exercise and Sphinx proof extensions, including installation and usage instructions. Updated references, credits, and feature pages to reflect inclusion in TeachBooks Template and Favourites. Improved consistency of external links and badges, and updated submodules to latest versions.
Moved basic features into a new 'Original Jupyter Book and Sphinx Features' section, consolidated and reordered feature sections, and updated references to external documentation. This improves the logical organization and clarity of the table of contents.
Split the TeachBooks Python Package and Deploy Book Workflow documentation into dedicated intro pages (teachbooks_intro.md, DBW_intro.md), update references and links throughout feature pages, and revise the _toc.yml structure to include new sections. Added clarifications to favourites and live_code features, improving organization and navigation for users.
Included the sphinx-accessibility extension in the Sphinx configuration and requirements. Updated the table of contents to reference the Sphinx-Accessibility manual for improved documentation coverage.
Integrated the sphinx-code-examples extension by updating _config.yml, _toc.yml, and requirements.txt. This adds support for code example features and links to its manual in the table of contents.
