[CCUT] add dimension URI and description

[basels]

Today we provide symbol only (derived from original QUDT v1 ontology)

i.e.: quantity:Time

qudt:symbol: T
qudt:description: Time is a basic component of the measuring system used to sequence events, to compare the durations of events and the intervals between them, and to quantify the motions of objects.

Originated in this issue.
