Interface: remove regions wrapper div

[ellatrix]

Description

This PR removes the wrapper div of navigateRegions and transforms the HoC into a hook adding the behaviour.

There's no need for the is-focusing-regions because the :focus selector should be enough and no region element should unintentionally be focussed.

How has this been tested?
