git-remote-helpers.txt: clarify command <-> capability correspondences
In particular, document 'list for-push' separately from 'list', as the former needs only be supported for the push/export capabilities, and the latter only for fetch/import. Indeed, a hypothetically 'push-only' helper would only need to support the former, not the latter.
