[Docs] - Add new pages

[jpudysz]

Description

Someone on Reddit gave me a cool idea: we could create a single page to train an LLM model about Unistyles 3.0. I think it would be a great addition!

Here is a global proposal to supprt llms.txt:

https://llmstxt.org/

Steps to Reproduce

Snack or Repository Link (Optional)

No response

Unistyles Version

3.0.0-beta.1

React Native Version

0.76.0

Platforms

Expo

Another improvement would be to add information about "Who should use Unistyles?" Most people tend to have trouble understanding the benefits and why they should transition from StyleSheet.
