deps: update webrtc to 0.11.0

[jxs]

Description

Also update rcgen to 0.13.1 as a direct dependency.

EDIT: Solved, see later comment.

Hey @jxs, I saw this PR as I was debugging some weird aarch64 cross compilation error for a outdated ring dependency. Following the dependency tree it appeared that my libp2p_webrtc dependency pulls that in, so it appears this PR fixes that 👍 .

However, I get the following error now and I can't quite figure it out:

error[E0599]: the method `map` exists for struct `Transport`, but its trait bounds were not satisfied

It's basically from the SwarmBuilder::with_other_transport:

        // ...
        .with_other_transport(|key| {
            Ok(libp2p_webrtc::tokio::Transport::new(
                key.clone(),
                libp2p_webrtc::tokio::Certificate::generate(&mut rand::thread_rng())?,
            )
            .map(|(peer_id, conn), _| (peer_id, StreamMuxerBox::new(conn))))
        })

I confirmed that this is only happening when switching from 0.7.1-alpha to this PR's 0.7.2-alpha. Using the following in Cargo.toml:

[patch.crates-io]
libp2p-webrtc = { git = "https://github.com/jxs/rust-libp2p", branch = "update-webrtc" }

Sorry for the previous comment. Seems like it was a distraction not related to this PR. I also had to patch the libp2p dep. Presumably otherwise the traits/structs do not line up. This is something the Rust compiler doesn't clearly convey yet apparently.

[patch.crates-io]
libp2p = { git = "https://github.com/jxs/rust-libp2p", branch = "update-webrtc" }
libp2p-webrtc = { git = "https://github.com/jxs/rust-libp2p", branch = "update-webrtc" }
libp2p-webrtc-websys = { git = "https://github.com/jxs/rust-libp2p", branch = "update-webrtc" }
