* Migrate to swift 6.0 & swift-gRPC 2.0 The following migrates to swift 6.0, and also migrate to swift-grpc 2.0 that uses swift-nio under the hood to provide nicer API and async await Adds sendable to enum & update @_implementationOnly imports to use internal imports * Address PR comments regarding misspelling & proper method naming.
