chore: Switch from edx-sphinx-theme to sphinx-book-theme

The edx-sphinx theme is being deprecated, and replaced with sphinx-book-theme.
This removes references to the deprecated theme and replaces them with the new
standard theme for the platform.

See https://github.com/openedx/edx-sphinx-theme/issues/184
