model test --tests *.fga.yaml does not work


When running

```
fga model test --tests *.fga.yaml
```

Only the first file gets processed. For it to work, *.fga.yaml need to be between quotes:

```
fga model test --tests "*.fga.yaml"
```

It should work both ways. The issue is that without the quotes, the shell is expanding it, and the CLI only gets the first one.
