Skip polygamma float16 test

[Stonepia]

We skip the polygamma float16 test due to a CPU issue: pytorch/pytorch#132386

This issue is caused by that the CPU result is not the same with CUDA/XPU. We believe that it should be fixed from the CPU side.

[daisyden]

Since this is a cpu case, it is ok to skip it.

The CI failure is not because of this PR, thus could be merged:
