Add Information on Beta Release Status for Auth.js v5 to Documentation

[kuchejak]

What is the improvement or update you wish to see?

The docs are missing information about the reasons for beta label of v5.

Is there any context that might help us understand?

The v5 npm package is marked as a beta release (next-auth@beta), but there is no clear explanation in the documentation about the reasons for this status (or at least I wasn’t able to find one).

Could you please add details regarding the beta label, specifically:

• The reasons for the beta label
• Whether there are potential security concerns or risks for production use
• Any known significant limitations or planned updates

This information would help users make informed decisions about choosing v5 over v4. I’m hesitant to use a library marked as beta for such a critical aspect as security/authentication without complete information.

Thank you!
