Jupyter Book version bug with custom templates

Jupyter Book latest version fails with custom templates

We use custom templates to compile the API documentation recursively for classes and modules through the _templates directory. This idea was taken from this SO post and incorporated in #514.

Jupyter Book versions greater than 0.13.3 break with this error:

Extension error (pydata_sphinx_theme):
Handler <function update_and_remove_templates at 0x7fdfb0437280> for event 'html-page-context' threw an exception (exception: toggle-primary-sidebar.html)

The bug seems to be described here and fixed here, but then it is again mentioned in a couple of other issues here and here.

Ultimately, this should be addressed one way or another in order to keep up with Jupyter Book and subsequent dependencies like the PyData Sphinx Theme.

How to reproduce

Build the documentation with Jupyter Book greater than version 0.13.3.

Just ran into this issue. Downgrading is not a great solution.

@TomaSusi just a heads up that this repository is not related to Jupyter Book, though we do use it for our documentation. Your message will get more eyes from the people working on this bug if you post in an issue such as executablebooks/sphinx-book-theme#729.
