docs: explain advanced OIDC provider controls

[atharva-appwrite]

What does this PR do?

Documents the OpenID Connect provider prompt and maximum authentication age controls in the OAuth 2 login guide. Clarifies where to configure them, when to use each option, and that they affect the provider authorization request rather than client callback handling.

This is intentionally scoped away from OAuth server / Sign in with your product documentation and the OAuth consent flow updates in #3090.

• bun run check
• git diff --check

Greptile Summary

This PR adds a new "Configure OpenID Connect authorization" subsection to the OAuth 2 login guide, documenting the prompt and max_age (max authentication age) parameters that Appwrite forwards to an OIDC provider's authorization request. It also fixes a missing trailing newline at end of file.

• The new subsection correctly describes all four standard OIDC prompt values (none, login, consent, select_account) and accurately notes that none must be used in isolation.
• The max_age description is technically correct per the OIDC Core spec and gives useful guidance on when to apply it.

Confidence Score: 5/5

Pure documentation addition with no code changes; content is technically accurate per the OIDC Core specification.

The change introduces only new prose in a Markdoc file. The OIDC prompt values and max_age description align with the OIDC Core spec, the heading hierarchy is correct, and the trailing-newline fix is harmless. Nothing in this diff touches runtime logic.

No files require special attention.
