docs: ref-manual: ref-variables: add links to terms in glossary

Before the move to Sphinx, it used to be possible to get a direct link to a
variable from the term glossary. It is very useful when pointing people to
a specific variable when manually looking for it in the glossary.

Let's add this "feature" back.
