Set Auth languageCode

[Jonsibua]

I need to set the languageCode in auth() to send action emails in the device language of the user.

Within the Auth instance languageCode would be the property to set. Firebase uses the method useDeviceLanguage() to set the language based on the device preference.

What is the current behavior?

React Redux Firebase does not support the method and also does not allow to update or set the language property.

What is the expected behavior?

To be able to set languageCode property.
