Expand manual on wikibase editing examples

[hugolpz]

Hello @kanasimi ,

I got a new usecase if you are still developping Wikiapijs.

I want to edit P2919 (I now know how) :

• Q9394#P2919

But I also want to specify sub-fields, I must therefor edit :

• P2919 label in sign language ---> 'Commons filename string'

  • P407 language of work or name ---> Q33302 French Sign Language

  There is no documentation on that :

  • https://kanasimi.github.io/wikiapi/Wikiapi.html#data

Is there another example I can show you?
