doc/fsck: clarify --connectivity-only behavior

On reading this again, there are two things that were not immediately clear to me: - we do still check links to blobs, even though we don't open the blobs themselves - we do not do the normal fsck checks, even for non-blob objects we do open Let's reword it to make these points a little more clear.
