ActionTypes<A extends Action<any>> Type Alias
A TypeScript type alias that uses conditional types (read: magic)
to represent the exact (literal) type of an action's type property.
More importantly, this can be used to determine a union type which represents the type string literal types for any action in a given ActionsUnion.
For example,
// given:
type MyActions = Action<"BANANA">
| ActionWithPayload<"APPLE", boolean>
| ActionWithPayload<"ORANGE", number>;
// then:
type X = ActionTypes<MyActions>;
// is equivalent to:
type X = "BANANA" | "APPLE" | "ORANGE";
