Description

.upper() method preventing matching CliffordGates because it is comparing against the .keys() method of the case insensitive dict which doesn't return all upper keys.

https://github.com/NVIDIA/cuQuantum/blob/main/python/cuquantum/pauliprop/experimental/operators.py#L170

i.e. "iSWAP".upper() = "ISWAP" which is not in supported gates (but "iSWAP" is)
