extended_stabilizer can't handle rz Clifford gates

[zlatko-minev]

Informations

• Qiskit Aer version: 0.14.1
• Python version: 3.11
• Operating system: Mac

What is the current behavior?

When running sim with rz gates, the extended_stabilizer fails, see code

Steps to reproduce the problem

from qiskit_aer.primitives import EstimatorV2 
qc = QuantumCircuit(2)
qc.rz(np.pi/2,0) # Clifford gates
qc.cx(0,1)
qc.measure_all()

simulator = AerSimulator(method='extended_stabilizer')
simulator.run(qc)

returns

Simulation failed and returned the following error message:
ERROR: CH::State: Invalid gate operation 'rz'. [Experiment 0] CH::State: Invalid gate operation 'rz'.

What is the expected behavior?

Ideally since we transpile all circuits down to rz gates, for verification, we want to be able to simulate these. Ideally the method could be able to resolve rz gates that are Clifford and ecr gates.
