Update Pennylane version requirement to one that is Qiskit 1.0 compatible

[bdg221]

Issue Description

This issue came from working on #2634 When looking to update the IBM hardware backend code in tutorials to move away from backend.run() that is now deprecated, the Pennylane IBMQ Backends includes:

# TODO: Remove the below comment when PennyLane supports Qiskit 1.0
# As of 03 May 2024, PennyLane is not compatible with Qiskit 1.0,
# but PennyLane plans to support the upgrade, soon

Checking requirements/requirements-pennylane.txt, the version used by Mitiq is:
pennylane-qiskit~=0.36.0
pennylane~=0.36.0

Current Pennylane version is 0.40.0 and Qiskit 1.0 is supported.

Looks like #2639 is the blocker for this.

We will have to wait for pennylane-qiskit to become compatible with qiskit>1.3. I tried reducing the qiskit version for mitiq in bc68ce8 but it led to multiple pytest failures.
