Fix giscus language mapping issue by enforcing strict pathname matching (#528)

Changed data-strict from '0' to '1' to prevent English pages from matching Chinese discussion threads. This ensures that:
- English pages (/tutorials/video/wan/wan2_2) will have their own separate discussions
- Chinese pages (/zh-CN/tutorials/video/wan/wan2_2) will maintain their separate discussions
- No cross-language comment mixing will occur

Fixes the issue where English tutorial pages were displaying Chinese comments due to fuzzy pathname matching.
