chore: add chainsafe libp2p maintainers in Javascript Team

[mpetrunic]

Summary

Seems like in https://github.com/multiformats/github-mgmt/pull/29 we forgot to add ourselves to Javascript Team.

Why do you need this?

So we can maintain js-multiaddr and other js related repositories

What else do we need to know?

DRI: myself
