🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Use a location state for a section link.

When the current document is not the first document in its section, s.active is true but s.href points to a different page. aria-current="page" then reports that different link as the current page. Use "location" for the active section, or omit aria-current.

Proposed fix 
-            aria-current={s.active ? "page" : undefined}
+            aria-current={s.active ? "location" : undefined}

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Suggested change

minimal, and validate.

In `@apps/landing/src/components/docs/DocsSectionNav.astro` at line 19, Update the
aria-current value in the section navigation link rendering so active section
links use "location" instead of "page", while leaving inactive links undefined.
