Protocols should be decorated with @typing.runtime_checkable to be able to use isinstance checks

[VolodyaCO]

Is your feature request related to a problem? If so, please describe it.

In qml-core, we make checks of the form isinstance(self._backend, WavefunctionSimulator). Apparently, in python 3.11+, these sort of checks cannot be made if the class is a Protocol unless they are decorated with @typing.runtime_checkable. Can we add these decorators to all protocols in orquestra-quantum to avoid this issue in the future?

How you envision the solution

Just add the decorator on top of every Protocol.
