Accessibility improvements

[oliverlloyd]

What does this change?

This PR adds 2 accessibility improvements

1. An aria label for the Recommend button
2. It removes FocusLock, improving keyboard access to the filters

Why?

We don't need to lock focus on these filters because it's logical to tab through them and the previous package we were using was causing focus to stop on two hidden divs, which would be confusing for people who use screen readers

Focus before

It's hard to see from the recording but focus is landing on two hidden divs when tabbing through the menus

Focus after
