♻️ (GroupCheckbox.tsx): update type for checked values in onChangeHandler for better type safety
Adding the packageManager field in package.json ensures that all developers use the same version of Yarn, promoting consistency across the development environment. Updating the type in the onChangeHandler enhances type safety by allowing both string and number types, which aligns better with the expected data structure.
