Breaking changes 💔

* The PennyLane-Rigetti plugin is only compatible with PennyLane v0.40 or below. To use Rigetti hardware with newer versions of PennyLane please use the [PennyLane-Braket plugin](https://amazon-braket-pennylane-plugin-python.readthedocs.io/en/stable/index.html) instead.

* Support for the `pennylane.operation.Tensor` observable is removed. This observable was deprecated,
and is fully removed in PennyLane 0.40.
