Add AI assisted code disclosure to homepage #2

Many users on bluesky try to minimize use of AI generated and assisted software. While this is not entirely possible due to the nature of bluesky itself having signifigant contributions by developers relying on AI assistance, a disclosure listed either on the homepage, or on the login page would be helpful so users can be informed of the nature of the software they are using before deciding whether or not to give the site access to their bluesky account.
