fix(vue-3): set editor's appContext.provide to forward inject chain (#5397)

Vue internally uses prototype chain to preserve injects across the entire component chain. Thus should avoid Object.assign or spread operator as it won't copy the prototype. All correct provides will be already present on `instance.provides`.
