Fix alignment of cluster count in cluster explorer

- Rely on inherriting parent's (`.child A`) line-height for both label and count
- This removes the different line-height approach between root (user & auth / users) and resource type (cluster explorer / any) side nav items
- This also fixes the `jump to..` list
