Add llms.txt

It could be great to add a llms.txt, like Svelte.
It would help llms to generate more accurate code by understanding daisyUI better.

I agree.
Currently there's a Text version for AI prompts link under each page (example) which gives the text version.
I should add one combined text version as well 👍
