Update for Qiskit 1.0

[frankharkins]

Description

This PR makes the minimal changes needed to get the tests working with Qiskit 1.0. It's possible this is all that's needed for full compatibility, but I'm not familiar with the repo so am just relying on getting the tests passing.

Most changes are just find/replace, the only exception being a tweak to add_qiskit_data to handle some removed attributes of Clbit.

We are not running all checks on PRs from extern, I will merge this now into a different branch, run the checks and then hopefully merge it into develop. Thanks again for the help!
