Handle generation of DRep information .jsonld file

Why

#120

What

• Handle logic behind generating .jsonld file

How

As the file itself and the data size won't impact the performance it should be handled client-side.

[MSzalowski]

Additional investigation of a better place to handle the logic might be needed. During the implementation of the feature it might occur that generation of such files would be much easier implementable on the backend side.
