Run images through ocr to allow mute words to apply to image content

Is your feature request related to a problem? Please describe.

Screenshots of posts from other platforms are a common pattern in bluesky. My mute words do not apply here and I am exposed to content that I'd wish to mute. Alt text doesn't always describe the text of the image.

Describe the solution you'd like

When users upload images extract the text in the image and place it a location that can be filtered by client apps. I think the place to change is here. https://github.com/bluesky-social/atproto/blob/c72145dbeb2d67068bc28c00a13447e0d382d121/packages/bsky/src/image/server.ts

Describe alternatives you've considered A conversation with Xblock labeler where we considered using labels but decided it would create roo many labels. https://bsky.app/profile/trashhalo.bsky.social/post/3lcegp2j6s22z
