fix #637

Description

adds native support for hyperlinks applied directly to image blocks. While Notion allows hyperlinks via image captions, exposing the link as a caption feels intrusive and affects the user experience.

To address this, we modify the asset-wrapper logic to properly detect and wrap images in anchor tags when a valid image_hyperlink is present.

Solution

1. Introduced getURLInfo()

• Determines whether the image should link to
  • a Notion page (/xxx pattern with UUID),
  • an external URL (validated using a URL regex).

2. Improved link handling logic

• Fallback order: imageHyperlink → caption
• Automatically wraps the image with <components.PageLink> only when a valid link is detected.
• Maintains support for internal Notion page routing via mapPageUrl.
