Support Searching All Versions of the Current Component

[rwinch]

The toggle for searching all versions or just this version should be displayed in the search results window.

I think it would also be good to call the toggle "Search All Versions"

You might also consider a link rather than a checkbox. Perhaps not bothering to save the previous selection.

I suspect that the typical flow will be:

• Land on the docs page
• Hopefully stick on the latest version, but possibly select an older release
• Search and expect results from that release

It's possible that you might be searching for a feature that was removed or something that was renamed. Only in those circumstances would you want to expand the search to cover all versions.

One advantage of a checkbox is that it can be remembered with local storage (as it is now), so a user doesn't have to keep clicking it if they want to keep searching across all versions.
