    Update cardano-ping to 0.2.0.7, so that `-j` is honored more often in ping command:
    the output of the info `network_rtt`, `handshake_rtt`, `negotiated_version`, and `queried_versions`
    is now written in JSON when `-j` is passed.

How to trust this PR

Run a local node, execute this command and observe JSON is written to stdout now:

→ export CARDANO_NODE_SOCKET_PATH="$HOME/dev/sanchonet/node.socket"
→ cabal run cardano-cli -- ping -m 4 -u $CARDANO_NODE_SOCKET_PATH -j
/home/churlin/dev/sanchonet/node.socket {"network_rtt":1.621e-5}
/home/churlin/dev/sanchonet/node.socket {"handshake_rtt":1.36611e-4}
/home/churlin/dev/sanchonet/node.socket {"negotiated_version":{"magic":4,"version":"NodeToClientVersionV16"}}
