Describe the bug

Due to use of a citation node, our layout breaks (scverse/cookiecutter-scverse#190)

That’s the fault of a docutils bug. We therefore need docutils 0.20 or later.
Docutils 0.20 is supported by Sphinx 7.0.1 and later.

We therefore need you to bump the maximum Sphinx version you support to 7.x (or unpin your maximum sphinx version)

Reproduce the bug

1. Use sphinx-book-theme
2. Create a sphinx document with a single citation as child of an element, e.g. via sphinxcontrib.bibtext’s .. bibliography:: directive.

List your environment

jupyter-book-theme 1.0.1, see above for the rest of the versions.
