The default value for `navigation_with_keys` will change to `False` in the next release. If you wish to preserve the old behavior for your site, set `navigation_with_keys=True` in the `html_theme_options` dict in your `conf.py` file. Be aware that `navigation_with_keys = True` has negative accessibility implications: https://github.com/pydata/pydata-sphinx-theme/issues/1492
