Description

In #2436 I've ignored the following cargo audit vuln: https://github.com/libp2p/rust-libp2p/blob/master/core/Cargo.toml

We need to upgrade to prost >= 0.8.0 to resolve this vuln, however lip2p is still on 0.7: https://github.com/libp2p/rust-libp2p/blob/master/core/Cargo.toml

Steps to resolve

1. Wait for libp2p to update.
2. Remove the ignore from CI.
