  1. fix: HTML4::Document.to_xhtml self-closing tags

    Commit 1d06b4f introduced NO_EMPTY_TAGS into
    SaveOptions::DEFAULT_XHTML which libxml2 ignored due to a
    long-standing bug in serialization.
    
    libxml2 v2.9.11 fixed that serialization bug
    (https://gitlab.gnome.org/GNOME/libxml2/-/commit/dc6f009) and started
    paying attention to the NO_EMPTY_TAGS save option, resulting in seeing
    output containing, e.g. `<col></col>` instead of `<col/>`.
    
    This commit updates the default XHTML save options to drop the
    NO_EMPTY_TAGS flag, restoring this behavior.
    
    Closes #2324
