Deno Fresh ConnectionRefused

Hi,

after doing `edgedb project init` I can run `edgedb ui` and see `Count` object and all, but when I run `deno task start` and open http://localhost:8000/ I get this error:

```
A client connection error occurred; reconnecting because of "waitUntilAvailable=30000". ClientConnectionClosedError: network error: ConnectionRefused: Connection refused (os error 61)
at RawConnection._onError (https://deno.land/x/edgedb@v0.21.1/_src/rawConn.ts:110:20)
at TLSSocket.emit (https://deno.land/std@0.114.0/node/events.ts:167:20)
at https://deno.land/x/edgedb@v0.21.1/_src/adapter.deno.ts:281:16
```

Instance is supposed to be running

```
edgedb instance list
┌───────┬────────────┬───────┬─────────────┬──────────┐
│ Kind │ Name │ Port │ Version │ Status │
├───────┼────────────┼───────┼─────────────┼──────────┤
│ local │ deno_fresh │ 10701 │ 2.0+88c1706 │ running │
```

I have no idea where to look next 😊

[edit] Actually I see same thing for Remix when running `npx edgeql-js`.

Reproduce the failure by running `edgedb project init`, then `deno task start`, and opening `http://localhost:8000/`; compare this with `edgedb instance list`, which reports the instance as running. Trace the connection configuration used by the Deno Fresh example and confirm that the application connects successfully without repeated ConnectionRefused errors.
