Code Review

This pull request updates the documentation for the DeepSeek-V3.2 tutorial, including model availability, installation instructions, and benchmark commands. The changes largely improve the tutorial's accuracy and clarity. I have one suggestion to make the installation process for Triton Ascend more robust by using pip to handle both download and installation of the wheel file.

[gemini-code-assist]

Using wget to download the wheel file and then pip install to install it is fragile. If the download is interrupted, the installation will fail with a potentially confusing error. It's more robust and simpler to let pip handle the download and installation in a single step.
