network: Upgrade `litep2p` to v0.6.2 (#4799)
This PR upgrades `litep2p` to the latest version and includes the two fixes: 1. Enables incoming DHT record validation with `litep2p` network backend. 2. Sets `TCP_NODELAY` flag on TCP & WS sockets in `litep2p` backend, as it is currently done in `libp2p` backend. --------- Signed-off-by: Oliver Tale-Yazdi <[email protected]> Co-authored-by: Oliver Tale-Yazdi <[email protected]>
