noAI. Yes. that

# What?

Add a global option to enable globally a `noAI`  and `noImageAI` `metatag` for Archipelago repositories + usable HTML tag/element everywhere (if you want to show that to the world)

This would require also "Language"/provided machinable endpoint with text/JSON-LD supporting this for a full disclaimer when enabled
