glossary: update description of "tag"
It is an unimportant implementation detail that ref namespaces are
implemented as subdirectories of $GIT_DIR/refs. What is more important
is that tags are in refs/tags hierarchy in the ref namespace.
Also note that a tag can point at an object of arbitrary type, not limited
to commit.
