Lambdas: use schemas and types from @dcl/schemas

[guidota]

Description

In order to be coherent with entity metadata among different services, we need to use the ones defined in @dcl/schemas

For example:

• https://github.com/decentraland/catalyst/blob/main/lambdas/src/apis/collections/types.ts#L8
• https://github.com/decentraland/catalyst/blob/main/lambdas/src/apis/collections/Utils.ts#L36

Wait for https://github.com/decentraland/common-schemas/issues/62 to be solved and use that schema/type.
