As an editor I want to be able to add and edit references in order to provide correct provenance for my data.
**Problem:**
Editing references in the Bridge directly is difficult in the first step because it requires editing of datatypes we don't support yet - especially Item links. We however still need to provide people with a way to add and edit references. We solve this in Step 1 by giving them a way to go to Wikidata to do it there.

**BDD**
GIVEN an existing statement
WHEN editing it in the Bridge
THEN a link is shown that lets me add and edit references on the repository
**Acceptance criteria:**
[ ] link to repository is shown near references
[ ] link is shown regardless of and how many references exist
[ ] link leads to statement group that is being edited with anchor (same URL as the edit link, just like for bail-out, preserving additional parameters like `uselang`)
[ ] link opens in new tab when left-clicked
