Make Skip to content link focus on main content

[Dananji]

Fixes #3774

When a user use tab key on Skip to content link in Firefox, it does not shift the keyboard to focus to main content, even though the view is focused. The user has to go through all the navigation links to reach the main content.

Changes proposed in this pull request:

• Use JavaScript on the click event of Skip to content link to change keyboard focus to the main content

Guidance for testing, such as acceptance criteria or new user interface behaviors:

• Open Hyrax in Firefox
• Press Tab key and then Enter
• Press Tab again to see the focus is skipped to main content

I'm not 100% sure what the intended behavior for this ticket is, but it is behaving in a way that seems to be working in most cases:

On the home page: it takes you to right before "share your work", skipping the navbar
on a works page: it takes you to right before "add to collection", skipping the thumbnails to be right after the work's title
on a collection page: it takes you to right before the "search subcollections and works" search bar, right after the title
On a search page, it takes you to right before the pagination controls at the top of the page, skipping the sidebar

However, I'm not sure it's really working in the dashboard, since it looks like for the pages there, it takes you out of the page, since the next tab is interacting with my bookmarks toolbar
