Merge pull request #210 from arnaucasau/fix-ci

CI was broken for four reasons:

    pylint was pinned to version 2.16.2 which doesn't support Python 3.12 and 3.11 officially
    Python 3.12 removed support for the imp library in favor of importlib and we were using a version of ipykernal that was importing the old library. The PR pins ipykernal to the first version supporting importlib. See this issue.
    The 'QuantumCircuit' object has no method 'bind_parameters' in qiskit 1.0 as we can see in #791 . This PR replaces the call to bind_parameters for assign_parameters as explained in the qiskit 1.0 release notes.
    The qiskit.execute function is not available in Qiskit 1.0 anymore -> Migration guide
