docs: remove beta banner and legacy SDK tab

[aimen74]

TL;DR

Removed the beta warning banner and legacy SDK documentation section from the docs configuration.

What changed?

• Removed the beta warning banner that displayed "⚠️Beta Docs – Welcome page, Payment Demo, Webhooks, and NEAR docs are ready. Use Cases, API, Resources, SDK, and Release Notes are still being revised. View stable docs →"
• Eliminated the "SDK (Legacy)" tab and its associated "🔧 SDK Documentation" group containing the legacy overview page

How to test?

1. Build and serve the documentation locally
2. Verify the beta warning banner no longer appears at the top of pages
3. Confirm the "SDK (Legacy)" tab is no longer visible in the navigation
4. Check that all remaining navigation tabs and pages load correctly

Why make this change?

The documentation has likely moved out of beta status, making the warning banner obsolete. The legacy SDK documentation removal suggests a transition to newer SDK versions, streamlining the documentation structure by removing outdated content.

Greptile Summary

This PR cleans up docs.json by removing the beta warning banner and the "SDK (Legacy)" navigation tab, reflecting that the documentation has graduated from beta status and the legacy SDK content has been retired.

• Beta banner removed: Eliminates the site-wide banner block that displayed a beta warning with a link to the stable docs site.
• SDK (Legacy) tab removed: Drops the "SDK (Legacy)" navigation tab and its single "🔧 SDK Documentation" group containing sdk-legacy/overview.

Confidence Score: 5/5

Safe to merge — the change removes two discrete, self-contained config blocks with no runtime logic.

The only file touched is docs.json, and both deletions (the banner block and the SDK Legacy tab) are isolated config entries that have no downstream dependencies remaining in the repo after PR #92 cleaned up the orphaned page and inbound links.

No files require special attention.

Important Files Changed

Filename	Overview
docs.json	Removes the beta banner config block and the SDK (Legacy) navigation tab; the orphaned page and inbound-link concern raised in earlier review was resolved in PR #92.
