docs: ref-manual: variables: remove sphinx directive from literal block

Literal blocks make sphinx take their text verbatim. This means that
directives cannot be used in literal blocks. This means :term:`S` was
printed as-is, without actually creating a link to the S variable
definition as would be expected outside of literal blocks.
