In:

• CREO2URDF – Build a GA on a self-hosted runner for automatically generate the urdfs #87

We added a GA that after a workflow dispatch pulls the latest ergocub-software and with the creo2urdf installed in the system generates the urdf and open a PR.

We would like to add the possibility to trigger it via repository dispatch as soon as a commit in a target repo is done
