[MedApp] add python registry

[philbucher]

Adding the python registry lists for the MedApp

@rubenzorrilla I am not fully sure what this does, my imports in the projParams also worked without this 🤔

Suggested change

	python_modelers_to_be_registered: List[str] = ["modelers.import_med_modeler.ImportMedModeler"]
	python_modelers_to_be_registered: List[str] = ["import_med_modeler.ImportMedModeler"]

As it is in the modelers list it will automatically add the corresponding modeler keyword. Long story short, in the list it is only required to add python_module.ClassName.

I copied it from the core where it is done like I do

Kratos/kratos/python_interface/python_registry_lists.py

Line 3 in 5bf5e40

"modelers.import_mdpa_modeler.ImportMDPAModeler"

I prefer to keep it consistent

The point is that in the core we have a submodule modeler coming from the corresponding subfolder within python_scripts. I didn't note that this is also the case in the MedApplication so you're right. Forget about my comment (I'd leave it as unresolved as "documentation").

Basically it will add all the Python entries in lists to the registry at the time the application is imported. Most probably you didn't notice any change as you're not using a registry-based factory.
