Fix bug missing some attributes on image component

[nhvu1988]

As I think the image block shoulds contain the original Strapi image information such as alternativeText, name, ext, provider_metadata ... instead of removing or customizing it. So it keeps the consistent with other plugins that may use them.

At least the preview URL is very important for improving SEO(in NextJS, for instance).

So, what could be a better solution?

However, it seems the Cloudinary plugin is not saving the previewURL.

Maybe adding an option to the plugin config to include the metadata could be a good compromise on the concern of the increased content size.
