Change Details

This task is about creating a subref of an existing main ref, using the VE reuse dialog. The final subref might look like: ``` <ref name="main-ref" details="p. 123" /> ``` based on a normal ref like: ``` <ref name="main-ref">Book name</ref> ``` Currently, we're only supporting the main+details form. Additional internal attributes may be necessary, and VE code which expects `isMainRefBodyWithDetails` or `isMainWithDetails` needs to be supplemented to support this other use case. Currently, these subrefs are being saved as if they are main refs: ``` <ref>p. 123</ref> ``` instead, the content should be saved in the "details" attribute. This work will mostly be in `ve.dm.MWReferenceNode.static.toDomElements`

==User story: As a VE user, when I use there's already a named reference with main content and I use the sub-menu in the reuse dialog to add a sub-reference for that reference then I can create a new sub-reference that's referring the main content of the former ==Acceptance criteria: GIVEN: ``` <ref name="book">Miller</ref> ``` WHEN I add a sub-ref reusing `main-ref` with the content `page 1` THEN a new sub-ref with the same name is added ``` <ref name="book">Miller</ref> <ref name="book" details="page 1" /> ```
