fix: extract label from image-only playground links

[rzzf]

https://npmx.dev/package/element-plus

Fixes an issue where playground links containing only an image (e.g. [![alt](img)](url)) resulted in a null label. Now uses the image's alt text as the label in such cases.

📝 Walkthrough

Walkthrough

The PR updates renderer.link in server/utils/readme.ts so that plainText is computed as a mutable value and, if empty, falls back to the text of a single image token when the link contains only that image. The data-title-intermediate attribute is only added when plainText or title is non-empty. A unit test is added to verify extraction of a label from an image-based CodeSandbox link.
