content routing example with node1.peerStore.patch won't work anymore because of updates to the peerStore class structure in "libp2p": "0.40.0"

- https://github.com/libp2p/js-libp2p/blob/master/examples/peer-and-content-routing/1.js

await node1.peerStore.patch(node2.peerId, {
    multiaddrs: node2.getMultiaddrs()
  })

I'm pretty sure this won't work because only the store implements these functions now: https://github.com/libp2p/js-libp2p-peer-store/blob/master/src/store.ts
