Migrate to picocolors (#1606)

Ref https://github.com/ai/nanocolors#nano-colors

Nanocolors is deprecated in favour of picocolors to avoid drama.
All dependencies already migrated. Also fixed one vulnerability.

The main change is step away from named exports and dual modules
support in favour of smaller package.
