Support for wikibase instances

[labra]

Wikishape started as a project with hard-coded support for Wikidata. However, we are more and more separating that behaviour to allow support for other wikibase instances.

• In settings, it is possible to change the endpoint to use a different wikibase endpoint

However, there are other features that still need to be fully checked to work with other wikibase instances.

Can you be more specific or give any tip on this? I can begin working on it.

With the changes in the back-end (https://github.com/weso/rdfshape-api/pull/299) and front-end (#42), users are able to use any Wikibase instance, with a couple of caveats:

• There's no golden rule to guess the SPARQL endpoint URL of a Wikibase, so users must know the base URL of their Wikibase instance and its SPARQL endpoint URL and pass them to the client. Otherwise, connection errors will occur.

• There's no tool in MediaWiki's API that allows to fetch the schemas of a Wikibase. That's why Wikidata schemas are still hard-coded (#10) and the Schema Info tool is the only one still limited to Wikidata.

For all other use cases, any Wikibase instance may be used and future problems can be addressed in other issues 🚀
