doc: use "`<literal>`"-style quoting for literal strings

"'<string>'"-style quoting is not appropriate when quoting literal
strings in the "Documentation/" subtree.

In preparation for adding additional information to this section of
git-for-each-ref(1)'s documentation, update them to use "`<literal>`"
instead.
