[ocamformat] Update to 0.13.0

We include the `version=0.13.0` field that should help users not to
use the wrong version. `disable=true` still seems a noop with `dune`.

There are some minor changes in the way comments are formatted; I'm
unsure if this is due to the `wrap-comments` option; as always; tweaks
to the config are most welcome.
