HTTP2TransportTests. testPeerInfoIPv4|testPeerInfoIPv6| testPeerInfoUDS test fail when the transport pair of `server=transportServices client=wrappedChannel`

[IrisG33]

Hi gRPC team,

I'm running the HTTP2TransportTests and encountered tests failures at https://github.com/grpc/grpc-swift-nio-transport/blob/main/Tests/GRPCNIOTransportHTTP2Tests/HTTP2TransportTests.swift#L1708-L1718

Here are some debug print:

--- print of `Transport.pair` and the `peerInfo`----
forEachTransportPair: server=transportServices client=wrappedChannel

peerInfo: PeerInfoResponse(client: GRPCNIOTransportHTTP2Tests.ControlService.PeerInfoResponse.PeerInfo(local: "ipv4:127.0.0.1:58904", remote: "ipv4:127.0.0.1:58038"), server: GRPCNIOTransportHTTP2Tests.ControlService.PeerInfoResponse.PeerInfo(local: "<unknown>", remote: "<unknown>"))

Other combinations succeed. I wonder is there some specific configuration required for these tests cases? Any hints would be helpful, thank you.
