[Feature] Automatically update project documentation

[zheliuyu]

Currently, the following projects obtain their documentation via git submodule.

• verl
• VeOmni
• LLaMA-Factory
• vllm-ascend
• triton-ascend
• ms-swift

https://github.com/Ascend/docs/blob/main/.gitmodules

However, when these projects obtain documentation via git submodule, a specific commit id needs to be manually specified. Is it possible to use a tool to retrieve the update status of these project documents and feed it back to Ascend/docs, so that the commit id of these projects can be automatically updated in Ascend/docs later?
