Update Community session 1210509

[YangWenhao3906]

Summary

• update the English and Chinese title and description for Community session 1210509
• add Runzhi He as a co-speaker, including his biography and Sessionize-hosted profile picture
• use the speakers' Chinese names on the Chinese page and note that both speakers are members of Professor Minghui Zhou's Open Source Software Data Analytics Lab

Why

The published session information needs to reflect the updated talk framing and speaker lineup.

Impact

This changes only the paired English and Chinese session source files described by the repository README. The schedule, track, room, and session language remain unchanged. Speaker pictures are referenced from Sessionize and are not stored in the repository.

Checks

• git diff --check
• Hugo build not run, as requested for this content-only update

@YangWenhao3906 please use the profile linke of sessionize for the speaker's picture, we don't store the picture in the repo.

@WillemJiang Sorry about that. I've updated both session pages to use Runzhi He's Sessionize profile image and removed the image file from the repository. This has been fixed in f7d6015. Thanks for pointing it out!
