Update and fix PyTorch docs

[ArkciaDragone]

• Updated the versions and releases in the scraper file
• Ensured the license is up-to-date
• Ensured the icons and the SOURCE file in public/icons/your_scraper_name/ are up-to-date if the documentation has a custom icon
• Ensured self.links contains up-to-date urls if self.links is defined
• Tested the changes locally to ensure:
  • The scraper still works without errors
  • The scraped documentation still looks consistent with the rest of DevDocs
  • The categorization of entries is still good

The documentation for PyTorch has unfortunately been overlooked for quite some time. While the recent update #2117 was intended to include the latest and significant versions, it has rendered the docs hardly useful. Specifically, the webpage layout has undergone changes prior to the update, which have not been addressed within the update either, resulting in the generated docs missing a substantial number of entries.

Examples of missing entries for inspection:
torch.stack, torch.sin, torch.nn.Module, torch.nn.functional.relu, torch.cuda.is_available

This PR aims to address this issue and also provide a named categorization mapping (which was previously absent). Although the code may not be flawless, I made an effort to include as many entries as I could think of while maintaining a concise structure for the list.

The PyTorch License, found at https://github.com/pytorch/pytorch/blob/main/LICENSE, appears to be more intricate compared to a typical 3-clause BSD license. In consideration of my limited familiarity with this subject, please make any necessary edits.
As a first-time Ruby code writer, I kindly ask for your understanding and assistance in adjusting my code to meet the standards of the repository.
