docs(tvix/castore): rename traverse_to -> descend_to r/6628

With the move of this code out into castore it has become apparent this
is a general descent inside the castore. Concerns like making sure the
whole Directory closure has been fetched/is fetched initially is nothing
this layer needs to worry about. We can handle this during substitution
of a new PathInfo, once there's store composition.

Closes b/270.
