The plugin is ignoring my custom file when specific the file with path.

As the document said we have to create a custom file at the root of the folder and it's working fine on my project,
Is it possible to move my custom file into another folder?

```groovy
staging {
secrets {
propertiesFileName 'properties/staging.properties'
}
}
```

The plugin is ignoring my custom file with the path and then somehow read from my release.properties instead.

Does anyone know how to read the configuration file from another folder?
