fix(button): rename 'small' variant to 'normal'

The button size that was previously named 'small' actually is more like
the 'normal' size variant in PrimeVue. For this reason we decided to:

- Change the default button size from 'small' to 'normal'
- Change all styling that was previously applied for 'small' to be
  applied for 'normal' instead
- Drop the 'small' variant as we don't have designs for that yet

This leaves the option open to introduce a smaller button variant in the
future.
