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.
