tokio feature adds libp2p-quic to dependencies

[nazar-pc]

Summary

tokio feature unconditionally introduces libp2p-quic dependency for unknown reason.

Consider following:

[dependencies.libp2p]
version = "0.54.1"
default-features = false
features = [
    "tokio",
    "yamux",
]

This way libp2p-quic is present in libp2p dependencies, if tokio feature is removed then libp2p-quic is no longer present.

Expected behavior

Only components explicitly requested are added to dependencies

Actual behavior
