Revert "[BE]: Update mypy to 1.10.0 (#127717)"

This reverts commit 30213ab0a7.

Reverted https://github.com/pytorch/pytorch/pull/127717 on behalf of https://github.com/huydhn due to I am not sure why but the failures look legit and they are showing up in trunk 30213ab0a7 ([comment](https://github.com/pytorch/pytorch/pull/127717#issuecomment-2144183347))
