Review the visual hierarchy of headings

[dashouse]

The interpretation of GOV.UK Elements typography styles may have been too literal. It states:

<h1 class="heading-xlarge">A 48px Bold heading</h1>

<h2 class="heading-large">A 36px Bold heading</h2>

<h3 class="heading-medium">A 24px Bold heading</h3>

<h4 class="heading-small">A 19px Bold heading</h4>

but in reality when looking at Gov.uk content the 36px size is rarely used, with the majority of h2's using the heading-medium size of 24px.

I think this is still relevant even in the migration to the Design System.
