Remove thumbnail setting from index page

[mintlify]

Documentation changes

Removes the thumbnail: preset: minimal setting from the index.mdx frontmatter. The center-aligned thumbnail looks off, so the index page now falls back to the site-wide thumbnail config in docs.json.

Note

Low Risk
Documentation frontmatter-only change with no runtime, auth, or data impact; only affects how the index page thumbnail is chosen for previews.

Overview
Removes the page-level thumbnail: preset: minimal frontmatter from the Introduction (index.mdx) page so social/link previews no longer use the minimal, center-aligned thumbnail that looked wrong on that page.

The index now inherits the site-wide thumbnail settings from docs.json instead of overriding them.
