Can't create instance while offline

It seems like it's not possible to create a new instance without active internet connection.

```
edgedb project init --server-instance test --non-interactive --server-version "1.4"
Found `edgedb.toml` in
Initializing project...
Checking EdgeDB versions...
edgedb error: failed to fetch JSON at URL: https://packages.edgedb.com/archive/.jsonindexes/x86_64-apple-darwin.json: HTTP error: failed to lookup address information: nodename nor servname provided, or not known
```

I used to have this issue before, but was able to solve by speicfying server version explicitly in the script (`--server-version "1.4"` part, though it was different version naming scheme back then). Now it seems to be not working again.

- EdgeDB Version: 1.4+0b7ba44
- EdgeDB CLI Version: EdgeDB CLI 1.1.2+0cdbb5f
- OS Version: MacOS 12.4 (21F79)

Steps to Reproduce:

1. Disconnect from internet
2. Run `edgedb project init --server-instance test --non-interactive --server-version "1.4"`
