chore(docs): tweak intro paragraph copy

[ndom91]

☕️ Reasoning

• Improve the intro paragraph a bit
• Add an <abbr> element to show definition on the "technical term" runtime agnostic

Copy

Auth.js is a runtime agnostic library based on standard Web APIs that integrates deeply with multiple modern JavaScript frameworks to provide an authentication experience that’s simple to get started with, easy to extend, and always private and secure!

This documentation covers next-auth@5.0.0-beta and later and all other frameworks under the @auth/* namespace. Documentation for next-auth@4.x.y can still be found at next-auth.js.org.

What do yall think? Open to changing the copy of course if anyone else has good suggestions 🙏. I do think the <abbr> thing is a good idea for more technical terms though.
