Describe the bug

Qubit 8 in https://github.com/Qiskit/qiskit-ibm-runtime/blob/main/qiskit_ibm_runtime/fake_provider/backends/hanoi/props_hanoi.json has T2 which is greater than twice T1. As a result, transpilation fails. (In addition to the noise being unphysical, which is not desired regardless of whether it causes anything to fail).

Additional Information
Possibly transpilation fails only starting from some optimization level.
