Improve responsive styles for secondary navigation component

[benfraserdesign]

We're exploring using this component at HMRC for a project exploring a new personal tax account for individuals (coming out of alpha as we speak). It has tested well in our 5 rounds of research - which included participants with accessibility needs and participants using a mobile/tablet.

As part of this work, we identified that the responsive styles could be improved - as noted in the component documentation. As a result, we made some minor adjustments (up to tablet dimensions) which resizes the navigation items to equal sized, centre-aligned elements.

Our service includes 4 items, which works well in user testing - but we'd recommend to not feature any more than 4 elements in the secondary navigation for it to work on smaller screens.
