Environment

• Qiskit version:

RC1

What is happening?

In <=1.4, BitLocation, being a namedtuple, is indexable. With no deprecation period, it is now not indexable.

How can we reproduce the issue?

You can reproduce by running this snippet on main

from qiskit import QuantumCircuit

circuit = QuantumCircuit(1)
circuit.find_bit(circuit.qubits[0])[0]

What should happen?

The snippet should not raise an IndexError.

Any suggestions?

Implement the getitem dunder.
