button-group-css: dev dependency on private package build-utils-css

[jstuyts]

The package @utrecht/button-group-css has a dev dependency on package @utrecht/build-utils-css, but the latter is not public. This results in failing builds:

@jstuyts Ik begrijp niet hoe dit kan gebeuren bij normaal gebruik, omdat die build-utils-css een devDependency is van @utrecht\button-group-css, dus die zou nooit geïnstalleerd moeten worden. Heb je @utrecht\button-group-css op de normale manier geïnstalleerd met npm, of heb je code gekopieerd?
