Update following removal of legacy opmath in Pennylane

[lillian542]

Context: PennyLane has removed the Tensor and Hamiltonian classes, so references to them also need to be removed in Catalyst. They were deprecated in 0.39, and have not been the default since before 0.36.

The new operator arithmetic equivalent for Tensor is Prod, and the new-op equivalent for Hamiltonian is LinearCombination, which is a subclass of Sum.

Description of the Change:

• We update catalyst to pin to the commit in PennyLane where legacy operator arithmetic was removed.
• We remove the sections of the code that reference and handle these operators.
• We also turn off all tests that need the Braket plugin, because the Braket plugin isn't compatible with the recent dev version of PennyLane, and won't be until after the 0.40 release.

Note: a shortcut story has been added to track reversing the test changes in this PR

Possible Drawbacks: We will not be running the OpenQASM braket test workflow with CI until after the 0.40 release.
