Code Review

This pull request updates the README.md and README_ZH.md files to include a Discord Group link and QR code in the contact section. The review feedback suggests standardizing the Markdown table formatting by adding leading and trailing pipes for consistency and localizing the 'Discord Group' label in the Chinese documentation to match the existing '微信群' label.

The table formatting here is inconsistent with other tables in the document (e.g., the options table in the WebUI section), which use leading and trailing pipes. Adding them ensures consistent rendering and better adherence to the project's Markdown style.

In the Chinese version of the README, it is more natural to translate "Discord Group" to "Discord 群" to match the "微信群" label. Additionally, adding pipes to the table maintains consistency with other tables in the document.
