fix(ui5-li): move default slot documentation from class to property level (#11898)

The default slot documentation was moved from the class-level JSDoc
comments to the actual slot property declaration for better clarity and
consistency.

This change improves documentation structure while maintaining the same
functional behavior - the slot is still defined with `type: Node` and
`"default": true`, which ensures that text content changes will properly
trigger component invalidation as expected for Node-type slots.

Relates to #11825
