Code Review

This pull request introduces a new 'Community' section to both README.md and README_zh.md, which includes an invitation to join a DingTalk group and embeds a QR code image. Review comments indicate that the dingtalk_qr_code.png image file is missing from the pull request and needs to be added to the docs/images/ directory. Additionally, the anchor links for the new 'Community' section in the table of contents (#-community and #-社区) are incorrect and should be updated to #community and #社区 respectively, as Markdown typically strips emojis and extra hyphens when generating anchor IDs.

The image dingtalk_qr_code.png is referenced here, but the image file itself does not seem to be part of this pull request. This will result in a broken image. Please add the image file to the docs/images/ directory within this pull request.

The anchor link for the new 'Community' section appears to be incorrect. Markdown headers with emojis typically have the emoji stripped when generating the anchor ID. The header ## 💬 Community will generate an anchor #community, so the link #-community will not work. Please remove the extra hyphen.

Suggested change

	- [Community](#-community)
	- [Community](#community)

[gemini-code-assist]

The anchor link for the new '社区' section appears to be incorrect. The header ## 💬 社区 will generate an anchor #社区. The link #-社区 will not work. Please remove the extra hyphen.
