Add /projects/:projectId/entity endpoint

[cazala]

This endpoint should return the entity describing the scene for a given project, only if the scene is SDK7

We should use the catalyst-client helpers to create the entity.

The JSON should look like this: https://worlds-content-server.decentraland.org/contents/bafkreiax2bdetek7sygpruvmbmplnax7il5nga3jrgcusxmr3uhljyk5dq
