Add Image Cropper widget documentation

[rahmanunver]

What

Adds Marketplace widget reference documentation for the Image Cropper widget at /appstore/widgets/image-cropper/.

The Image Cropper widget lets an end-user crop, rotate, zoom, and convert an image to grayscale in the browser, saving the result back to the bound image attribute. It replaces the legacy Image Crop module.

Details

• New page: content/en/docs/marketplace/platform-supported-content/widgets/image-cropper.md
• Follows the standard Marketplace widget page structure (Introduction → Features → Limitations → Configuration by property tab/section → Usage → Styling → Read More).
• Property documentation mirrors the widget's property tabs and sections: General (Source, Crop area, Events), Dimensions (Canvas), Behavior (Interaction, Buttons, Zoom), and Output.
• Includes two demo GIFs under static/attachments/appstore/platform-supported-content/widgets/image-cropper/.

Note

The Marketplace component link in the introduction uses a <COMPONENT_ID> placeholder that needs to be filled in with the widget's actual Marketplace component ID before merge.

Hi @rahmanunver . Can you also change the Image Crop module to relflect its Legacy (which I assume also means deprecated?) status?

It's pretty easy, you just add a line to the metadata and an alert box at the top like this example here.
