feat: allow for default select icon to be hidden

[MentalGear]

I'd like to propose adding an option to switch off the default select icon in the Select Input.
This would allow using custom icons with ease by providing them right in the slot, or none at all if the dev prefers.

Example:

Just noticed that the element received an update before my code adjustment - let me know if you agree with the general idea and we can see to update it to the new version. Cheers !

Hey there, I'm cool with adding this prop.

Let's make the prop withIndicator defaulting to true. These changes should apply to both the new-york and default styles.
