Cross-space resources: Updated format of resource links contains environment information

The CRNs (Contentful Resource Names) used in ResourceLinks for References across spaces now include information on which environment the entity belongs to by default when the environment is master, or another ID when referencing a new cross-space entry.

This change accommodates the new support for environments when linking to cross-space references, and ensures we are consistently representing the resource link information whenever a new reference is linked.

Old format

crn:contentful:::content:spaces/:spaceId/entries/:entryId

New format crn:contentful:::content:spaces/:spaceId/environments/:environmentId/entries/:entryId
