Changes

• packages/fedify/src/runtime/contexts.ts:
  The JSON-LD context for FEP-5711 (https://w3id.org/fep/5711) was added. This context defines the eight new inverse properties, ensuring that the Fedify library can correctly parse and understand them when they appear in a Collection object.
• packages/fedify/src/vocab/collection.yaml:
  The eight inverse properties (likesOf, sharesOf, repliesOf, inboxOf, outboxOf, followersOf, followingOf, and likedOf) were formally defined in the vocabulary. This step is crucial as it enables the Fedify library to properly validate and interact with these new properties.

Benefits

Improved Interoperability: By implementing FEP-5711, Fedify can now seamlessly interact with other Fediverse servers that use this standard, improving data consistency and network compatibility.
