Github Codespaces: spawn xdg-open ENOENT on wrangler dev

Really excited about this! I gave this a spin in Github Codespaces and ran into the following:

@irvinebroque ➜ /workspaces/project (main ✗) $ wrangler dev src/worker/index.ts
/usr/local/share/nvm/versions/node/v17.1.0/lib/node_modules/wrangler/wrangler-dist/index_node.js:27064
            throw ex;
            ^

We definitely want to support environments like github codespaces (and codesandbox, stackblitz, all of them). For one, ee should have a better experience so this doesn’t crash immediately like it does. As a workaround, you can start the command with --local so it runs fully on the machine itself. That said, you might not be able to automate the opening of devtools either. We’ll get better at this. Leaving this issue open until we have a better story.

Fixing the opening link part is simple, the problem which I’m not sure how should be properly solved is the localhost callback for auth.

What I think is probably easiest is accepting user input to retrieve the callback URL.

Something like:

💁 Opening https://dash.cloudflare.com/oauth2/auth?response_type=code&client_id=${CLIENT_ID}&redirect_uri=${CALLBACK_URL}&scope=${SCOPES}&state=${STATE}

Failed to launch browser (spawn xdg-open ENOENT)

Please insert callback URL:
$ http://localhost:8976/oauth/callback?code=${CODE}&scope=${SCOPES}&state=${STATE}

Not ideal but would at least support codespaces, servers, etc to authenticate through OAuth.
