## PR-Codex overview
This PR focuses on updating the `sidebar.tsx` file by modifying the structure of the navigation item for dedicated support, and enhancing the `globals.css` file by adding new styles for code elements in light and dark themes while removing redundant styles.

### Detailed summary
- In `sidebar.tsx`, the `href` property for the "Get Dedicated Support" navigation item was removed.
- In `globals.css`, new styles were added for `code span` elements in both light and dark themes.
- Redundant styles targeting `.shiki` and `code span` were removed to streamline the CSS.
