Slate v3 or Slate v2 update proposal for Boolean option types in Chat Input Slash Commands

[Colton1070]

Currently, the Boolean option is essentially a String option with True or False choices. I believe that it would look and feel better for these option types to have unique UX for selecting true or false.

If the option is required, it could look like a toggle switch that can be pressed on mobile or selected on PC by just tapping the option. Similarly, an optional Boolean can be enabled by tapping on the option and disabled by tapping on the option again (and could be represented by a ballot box.

This would also resolve the current inconsistency with language support, as toggles/ballot box would be a universal way to communicate the boolean's value.
