Change content schemas to require alt text with an image

[outofambit]

In our content schemas, it is possible to provide an featured image but no alt text for it. Our schemas hold them separately as in:

featuredImage: image().optional(),
featuredImageAlt: z.string().optional(),

a schema like this would prevent authors from adding an image without also including alt text:

featuredImage: z.object({
    src: image(),
    alt: z.string()
}).optional(),

which also makes it possible to provide a default with accurate alt text, as in:

featuredImage: z.object({
    src: image(),
    alt: z.string()
}).optional().default({
  src: PlaceholderImage
  alt: 'the p5 logo in a grey box'
}),

This makes sense. I am the one that originally switched it from this and when I read this I was like "yeah that's a great idea. I have no idea why I changed it to begin with" but then I just tried switching to this approach and it isn't possible.

The return of "image" is much more complex than a single src string. It includes file information related to the optimization and static build and it isn't transformed into that more complex object until build time. I may be missing something but I just tried for a while and there wasn't a way to package the image() into anything other than a base property of the schema. This would explain why the Astro documentation doesn't put the image() in a property of an object.

Edit: Still trying to figure out an elegant way to do this. Could by another mistake that I am making. Will update if I find a way
