Upgrade Canvas to v0.12.0, peer with Explorer

[raykyri]

This PR upgrades the Canvas version to 0.12.0, and adds a default peering configuration pointing to https://common-explorer.canvas.xyz/, which is autodeployed from https://github.com/canvasxyz/canvas/tree/main/examples/common-explorer#common-network-explorer.

• v0.12.0 changes generic types on the Canvas<T extends ModelSchema> object, which is the main "app" abstraction for Canvas, but doesn't otherwise introduce any major new changes.
  • No commonwealth changes were required for this upgrade.
• v0.11.0:
  • libp2p changed their API for creating private keys and peer ids (PR). Canvas adopted the new API in version 0.11.0, so we need to update references to PEER_ID to LIBP2P_PRIVATE_KEY instead. The underlying format of the PEER_ID env var has not changed.
  • The way we initialise the Canvas object has changed, we now pass libp2p-specific config fields to app.startLibp2p.
  • The constructor for SIWESigner has changed slightly, if we create a SIWESigner without a signer config value then it generates an ethers wallet and then saves it in local storage. This does not affect how Commonwealth works because we always pass in a signer config value (which would be some kind of handle to the MetaMask/WalletConnect/etc browser extension) but it meant that some of the test fixture code had to be changed to explicitly always create a new ethers wallet.

This also changes the logger inside packages/commonwealth/scripts/create-peer-id.ts to use console.log instead of the builtin logger, to avoid importing @hicommonwealth/core...

Link to Issue

Closes: #8919, #7520.

Test Plan

• pnpm start, create a comment with an account with a live session key, and it should show up on common-explorer.canvas.xyz.

Deployment Plan

• Delete the old PEER_ID private key inside ENV variables, and add a LIBP2P_PRIVATE_KEY generated by running ./create-peer-id.ts in packages/commonwealth/scripts, and slack @raykyri with the resulting public key (printed 12D3Koo... above the private key).

Other Considerations

• n/a

Why? Did importing core cause issues?
