Handle long links in uui-ref-node

[bjarnef]

Description

Handle issue described in umbraco/Umbraco-CMS#20457

It have highlighted container with max-width: 420px and the the button in uui-ref-node itself.
However it seems e.g. slots like "actions" should be considered in full width, so it fit within a container size.

Perhaps uui-ref-node needs a wrap property/attribute - in case it sometimes need multi-line details.
