Please update dependencies

[nazar-pc]

The dependencies used here are outdated and should be updated:

• ring 0.16 is old and doesn't compile on some targets + results in duplicated dependencies been built for Substrate users
• rustls 0.20 is also old and has known CVE attached to it, which while not applicable, requires active suppression and results in duplicated dependencies for Substrate users

The most frustrating thing is that we don't even use litep2p, it gets pulled with Substrate unconditionally and we have to struggle from this for no reason 😕

Please consider updating these ASAP and bump the version in Substrate accordingly
