Why needed: The way the EDTF datatype is exposed in RDF output has changed;. Before more users on the platform start using the extension, this should be fixed. The extension is actively in use by a small number of wikis on the platform, and this is likely to increase.

Impact: If we do not fix issue, the RDF output will continue to be wrong for an increasing number of wikis that adopt the datatype. Data could theoretically need to be reloaded into all of the query services for all of the Wikibases that use this datatype. Catching the issue earlier rather than later will save time.

Ultimately the line that fetches the code for wbstack is https://github.com/wbstack/mediawiki/blob/main/wbstack/sync/02-fetch.sh#L75

Acceptance Criteria

• Latest version of the EDTF datatype extension is deployed on WBstack (as of writing of this ticket, v1.2.0)
