Fix generation of IOMDHAL.yml
This one is a special case where the superproject name mismatches the corresponding Env (and thus Components) file. Our own CI script also didn't previously support the *removal* of an autogenerated YAML file. This should be a rare occurrence, but it's best to automate this also. Also support force-pushing to the submodule; this will be required in most cases where the pipeline was triggered by a force-push to *this* project.
