[docs] Improve table of contents cmd+click

[Janpot]

Related to #18756

Just relying on findActiveIndex seems to be enough. This code would activate items when cmd+clicked (or middle click) without scrolling.

Alternatively we could pass the click event and check for .metaKey and middle mouse button, but that seems overly complex to me.

The logic was added to work around edges: try https://deploy-preview-18765--material-ui.netlify.com/components/checkboxes/#api and click on the "API" anchor.

I would prefer that we ignore these cmd+click events instead:

Also, I'm wondering if we shouldn't follow react-router link logic rather than next.js link logic
