Support new libp2p WebTransport transport for experimentation

[BigLep]

Done Criteria

A Kubo user can enable the WebTransport transport in go-libp2p. It should not be on by default.

Why Important

WebTransport opens up better browser connectivity to Kubo nodes. We want to enable experimentation to begin here.

User/Customer

Users who are attempting to connect browser js-ipfs nodes to Kubo nodes.

Notes

1. There are implementation notes on how this should be exposed to users in https://filecoinproject.slack.com/archives/C03L0G3B4RX/p1663347840245489
2. The go-libp2p tracking issue for this work is: [Tracking Issue] Experimental WebTransport Transport libp2p/go-libp2p#1717
3. JS work will be happening in https://github.com/libp2p/js-libp2p-webtransport
4. There should be corresponding documentation about this functionality but this can come once we actually have more docs in libp2p and an ability for a browser js-libp2p node to connect to a Kubo node. Here is the docs side: Document how to connect browser nodes with Kubo nodes using WebTransport ipfs-docs#1286
5. This depends on chore: bump go-libp2p v0.23.1 #9285
