Describe the changes you are looking for

We should be able to choose the inputMethod when we're using the InputField the same way we're able to use it with the NumberField, similar to what we have on Android Docs https://developer.android.com/develop/ui/views/touch-and-input/keyboard-input/style, we should be able to choose the keyboard type (or inputMethod) when using any type of input.
