Is your feature request related to a problem? Please describe.

".config" extension is more proper when it comes to json settings. I have been wondering why it has been "Settings.XamlStyler". It'd be more consistent if it would be "*.config".

Describe the solution you'd like

• Accept "xstyler.config"

Describe alternatives you've considered

• Alternatively accept "xamlstyler.config"

Additional context

None
