Fix `autify update` with Windows and brew

On Windows:

```
Run autify update
@autifyhq/autify-cli: Updating CLI... not updatable
```

With brew on GitHub Actions:

```
Run autify update
@autifyhq/autify-cli: Updating CLI... fetching manifest

@autifyhq/autify-cli: Updating CLI from 0.10.0-beta.0 to 0.10.0-beta.0-2f002ba (beta)... done

triggerUncaughtException(err, true /* fromPromise */);

[Error: ENOENT: no such file or directory, open '/Users/runner/.local/share/autify/channel'] {
errno: -2,
code: 'ENOENT',
syscall: 'open',
path: '/Users/runner/.local/share/autify/channel'
}
```

Note: `autify update` works on my macOS laptop (`autify` is installed via brew).
