[Bug]: focus does not reset upon navigating to a new API docs page

Description

Encountered an error when navigating to a new API docs page.

When I click on a navigation element (e.g., clicking on a link to navigate to the "next" package), the focus stays on the navigation element. This means that, for those with screen readers, they are unable to begin tabbing through the new page's content. Instead, hitting TAB picks up where they left off on the previous page.

The preferred approach here is that we reset the focus to the top of the page to the skip-link so that users can either TAB through navigation or skip to the main content.
