chore: include if direct connection is over private network in ping diagnostics (#15313)
Whilst the `networking-troubleshooting` docs page already mentions thata direct connection can be established over a private network, even ifthere are no STUN servers, it's worth this is the case at the end of theping output.This also removes a print statement that was dirtying up the diagnosticoutput, and corrects the name of the `--disable-direct-connections`flag.
