fix(providers): conform Apple

[balazsorban44]

☕️ Reasoning

"Sign in with Apple" is not the smoothest thing to implement. The DX for setting things up for development is subpar considering the UX they uphold themselves for their users. It requires extra hops on every corner.

But here it is. With some hacks in the core library - since Apple is unable to follow the OIDC spec -, it is now fully working again. I'm sorry for those who needed to implement hacks for it before.

As part of this work, we've also worked on a way to generate the client secret with a community member, since Apple expects it to be a JWT. You can run npx auth add apple in the root of your project, and it will give you a step-by-step on how to do it. At the end, it will add the AUTH_APPLE_ID and AUTH_APPLE_SECRET to your env file as well.

Feedback on it is appreciated!

Huge thanks to @ChrGrb for the preliminary work in #8428 and #8189.

Authjs (next-auth) 5.0.0-beta.25 worked for me for Apple login today, even after upgrading to Next 15.0/React 19.0. Many thanks for your efforts on this.
