sphinx-book-theme shows incorrect theme and theme_version

[72757373656c6c]

Describe the bug

Context

In conf.py, when footer_content_items is set to:

footer_content_items": ["copyright", "last-updated", "sphinx-version", "theme-version"]

Expectation

I expect the theme and theme-version to be "Sphinx Book Theme":

Built with the Sphinx Book Theme 1.1.2.

Bug

But instead the theme and theme-version are PyData:

Built with the PyData Sphinx Theme 0.15.2.

There were no console errors.

Problem

The sphinx-book-theme shows incorrect theme and theme_version. The correct theme and theme_version should be shown.

Reproduce the bug

1. In conf.py set the theme: html_theme = "sphinx_book_theme"

2. In conf.py add footer_content_items": ["copyright", "last-updated", "sphinx-version", "theme-version"] to html_theme_options.

3. In a terminal type make clean ; O='-E -W --keep-going' make html

4. View the html output in a browser, specifically the footer content.

A workaround is to do the following:

1. In conf.py add "footer_content_items": ["copyright", "last-updated", "sphinx-version", "extra-footer"]

2. Add "extra_footer": '<p class="theme-version">Built with the <a href="https://sphinx-book-theme.readthedocs.io/en/stable">Sphinx Book Theme</a> 1.1.2.</p>' to html_theme_options.
