Replace traits find_resource with importlib.resources in examples

Does this require the examples to to moved inside the package or to make examples a python package itself with an __init__.py file? (this is already planned when we contribute them to etsdemo). I am having some trouble getting things to work without this, and I believe this is the case (at least with importlib_resources / importlib.resources pre python 3.9 or something like that?)
Also we should use importlib_resources for the time being correct since importlib.resources was only introduced to the standard library in python 3.7
