Hardcoded directory

Hello,

I just ran `./setup-test-environment.sh setup` and got

`[ERROR] AppFlowy-Web-Premium directory not found at: /Users/weidongfu/Documents/AF/AppFlowy-Web-Premium`

This is because of this

https://github.com/AppFlowy-IO/AppFlowy-Web/blob/11c20e59263dcfd07f6261177368a107610d739d/setup-test-environment.sh#L32

I changed the ENV to my local setup but still ran into

```
✘ appflowy_web Error manifest for appflowyinc/appflowy_web:local-11c20e5 not found: manifest unknown: manifest unknown 1.9s
Error response from daemon: manifest for appflowyinc/appflowy_web:local-11c20e5 not found: manifest unknown: manifest unknown
```

What should I do when I just want to start a localhost version to check things out?

Greetings
