docs: CSS: make cross-reference links more evident 

The Sphinx Alabaster theme uses border-bottom to mark reference links; the
result does not render correctly (the underline is missing) in some browser
configurations.  Switch to using the standard text-underline property, and
use text-underline-offset to place that underline below any underscores in
the underlined text.
