Pull request overview

This PR aims to fix broken documentation links in PyTorch API comparison documentation (tasks 80-84 from issue #7735). The links were broken due to PyTorch official documentation structure changes. The PR updates both external PyTorch documentation links and internal PaddlePaddle API reference links.

Changes:

• Updated PyTorch documentation links from pytorch.org to docs.pytorch.org domain with corrected paths
• Updated PaddlePaddle internal API documentation links to use new URL structure with anchor-based navigation
• Fixed links in 5 API difference documentation files related to autograd functionality

标题可以去掉’-part‘：我搜索了这些错误链接，不存在于Paddle中，即不用修改第二个库，那么此PR为该404链接最后一条PR~
