Update Playground to support Cadence 1.0

[gregsantos]

Once playground api uses the new emulator that supports 1.0 (Im not sure if we can do this now)
After which, we can update all the reference templates. Then update all the urls to reference templates. This might effect cadence cookbook
Users: old projects will fail to deploy and force users to fix their projects.
