Use new Session.from_id() method in qiskit-ibm-runtime (#421)

* Use new `Session.from_id()` method in qiskit-ibm-runtime

* Bump qiskit & qiskit-ibm-runtime versions

qiskit-ibm-runtime depends on qiskit>0.44.1, so we are forced to
bump qiskit as well for the minimum version tests to pass.

* Bump rustworkx version

rustworkx 0.13 is required by qiskit 0.44.1
