Disable taxonomy, term, and RSS pages

`disableKinds = ["taxonomy"]` only disables the taxonomy list page;
post-Hugo-0.73 individual term pages are a separate kind. The site
declares no taxonomies, so neither list nor term pages have content,
but the config now matches its stated intent. Disabling RSS also
suppresses an empty `index.xml` that nothing subscribes to.
