Fix typo in "Berry: color of skin"

Follow-up from archived issue tracker.

In the Vitis ontology, the "Berry: color of skin" trait (CO_356:2000007) has "Entity=Berry skin" and "Attribute=Shape". I think it should be corrected into "Entity=Berry skin color" and "Attribute=Color", or something equivalent.

(It may originally be due to a copy-and-paste from the "Berry skin" trait (CO_356:2000182).)

When making this edit, thanks for also updating the version of the ontology itself on GnpIS website from v2 to v2.0.1.
