fix(create-next-app): click event blockage under 1024px by adjusting z-index (#52074)

### What?

Fixed a bug that the title of the topmost Docs was unclickable when less than 1024px.

### Why?

This appears to be due to the fact that these clickable elements are overlapped by the logo image wrapper in Next.js, preventing the propagation of click events for these elements.

### How?

To mitigate this problem, this PR assigns a z-index of -1 to the Next.js logo image wrapper. This change ensures the wrapper is placed beneath the clickable elements, thereby preventing it from blocking click events on smaller screens.
