Lgtm @peterhnm! I moved it to ready :)

Since Nx follows a "single version policy" it is not possible to manage two versions of the same lib in one repo. Therefore it is necessary to wait until DigiWf Form Builder and Renderer is migrated to Vue 3 to migrate Miranum Json Forms.

We already migrated miranum-json-forms into the monorepository. There's nothing further to do
