Code Review

This pull request updates the English and Chinese documentation for VBench. The changes include adjusting markdown header levels, correcting a typo in the Chinese documentation, removing a trailing comma in a code block, and updating the Hugging Face download URL for the Tag2Text model to its correct repository path. There are no review comments, so I have no feedback to provide.
