Remove all the logic for the special handling of this submodule, and
treat it instead a regular Git submodule.
This commit updates the submodule to latest, removes the --no-pull
functionality, and removes the ignore of the submodule to make
developers aware
To ease maintenance, add also dependabot to pay attention to the future
updates of the submodule.
