chore: update libp2p

[Stebalien]

Probably best to wait until after the RC to merge this, but I figured we could get the ball rolling to catch any early test failures.

Well, this is going to be fun:

1. We can't update libp2p till we update boxo.
2. Boxo has changed a bunch of API code, so we can't update that without updating https://github.com/filecoin-project/kubo-api-client.

So, I'm just going to try to kill off https://github.com/filecoin-project/kubo-api-client.
