Pulse drawer does not work with V2 backends from IBM Runtime

[nonhermitian]

Environment

• Qiskit version: 1.1
• Python version:
• Operating system:

What is happening?

from qiskit import QuantumCircuit, transpile, schedule
from qiskit.visualization.pulse_v2 import draw
from qiskit_ibm_runtime import QiskitRuntimeService

service = QiskitRuntimeService()

backend = service.get_backend('ibm_sherbrooke')
 
qc = QuantumCircuit(2)
qc.cx(0, 1)
trans_qc = transpile(qc, backend)
sched = schedule(trans_qc, backend)
 
draw(sched, backend=backend)

File ~/mambaforge/envs/qiskit/lib/python3.11/site-packages/qiskit/visualization/pulse_v2/device_info.py:113, in OpenPulseBackendInfo.create_from_backend(cls, backend)
110 defaults = backend.defaults()
112 # load name
--> 113 name = backend.name()
115 # load cycle time
116 dt = configuration.dt

TypeError: 'str' object is not callable

How can we reproduce the issue?

do above

What should happen?

It should draw

Any suggestions?

It is obviously just the change from method to attribute in the classes
