Initial ticket content
I would like to have my own wikibase instance with ShEx support as has been recently added to Wikidata...what would I need to do that?
The EntitySchema extension should be loaded in the bundle image for wikibase.
This should only happen for version of mediawiki / wikibase where the extension was ready / released UNLESS compatability is checked and EntitySchema works on previous version of mediawiki / wikibase, then it could also be added there.
This is likely only the current / latest release? We might actually have to wait for the next release?
See other simple extensions for how to include: for example WikibaseImport. It seems likely that you'll need to the following steps:
In Dockerfile download copy extension to composer image install deps copy to final image in config files add required default settings for extensions update readmes to include new extension and links to docs
