Qualify constructor of CUDAAllocator in cuTENSOR extension

[giordano]

This fixes the warning

┌ TensorOperations → TensorOperationscuTENSORExt
│  WARNING: Constructor for type "CUDAAllocator" was extended in `TensorOperationscuTENSORExt` without explicit qualification or import.
│    NOTE: Assumed "CUDAAllocator" refers to `TensorOperations.CUDAAllocator`. This behavior is deprecated and may differ in future versions.
│    NOTE: This behavior may have differed in Julia versions prior to 1.12.
│    Hint: If you intended to create a new generic function of the same name, use `function CUDAAllocator end`.
│    Hint: To silence the warning, qualify `CUDAAllocator` as `TensorOperations.CUDAAllocator` in the method signature or explicitly `import TensorOperations: CUDAAllocator`.

Thanks for that fix, looks like this should have been imported anyways. I didn't know this didn't previously give warnings. Appreciate the update!
