[feat] Install this as DDEV addon via `ddev get ddev-gitpod`?

Hey, just a quick idea, would be cool to install this via the following:

```
ddev get shaal/ddev-gitpod
```

See: https://github.com/drud/ddev-addon-template

(Recently done this myself for custom commands https://github.com/mandrasch/ddev-addon-deployer-dep, it's quite simple)

Cheers!
