So that users can use the new Entity Schema data type (T332139) it needs to be enabled on Wikidata.

Acceptance criteria:

• The new EntitySchema data type (created in T332139) is enabled on Wikidata that allows linking to EntitySchemas in statements

Acceptance criteria covered in T332139:

• Only existing EntitySchemas can be selected as values
• Link text should be the ID (or label if possible) of the EntitySchema
• The new datatype should be added to Special:ListDatatypes

Notes:

• The value input of a statement should have the ability to use EntitySchema ID as well as the label of the EntitySchema. If the EntitySchema label is unable to be used in this instance the EntitySchema ID is acceptable.
• This property proposal has been approved and is awaiting this datatype: https://www.wikidata.org/wiki/Wikidata:Property_proposal/Shape_Expression_for_class
