Problem:
As of the implementation ADR 0003, EntitySchema makes use of Wikibase's hooks and service classes for adding a new Datatype.
In order to ensure the reliability of EntitySchema, and prevent regressions due to changes in Wikibase, we would like to add EntitySchema to a daily Wikibase CI test run (as opposed to every change) as described in T285049: Run CI tests daily on master for ungated extensions.
Acceptance Criteria:
- A daily Wikibase CI test is configured to run together with EntitySchema
