fix: Made ToggleButton.Group TS compatible

[gedu]

fix: Now you can use ToggleButton.Group with Union Types and Enums (default string)

Summary

Before you couldn't use Union types or enums without TS complaining about the type

type Fruits = 'watermelon' | 'strawberries' | 'apple';

with this new change, TS will get the right type and won't complain

Test plan

• Use different types, like string, enums and union types
• Check if the IDE get the right type
