fix: Remove SwitchField's labelPosition prop, as it has no effect

[behowell]

Current Behavior

The SwitchField control inherits the labelPosition prop from Switch. However, the label prop goes to the field and not the Switch, and so the Switch's labelPosition prop has no effect.

New Behavior

Omit the labelPosition prop from SwitchField to avoid confusion.
