fix: Correctly set type for false or 0 constants

Description

Fixes #1647

I've expanded the const specification to include false and 0 constants. Before this change, the models were generated as:

export interface BooleanConst {
  value: true;
  valueFalse: boolean;
  valueNullable: BooleanConstValueNullable;
}

export interface IntegerConst {
  value: 1;
  valueNullable: IntegerConstValueNullable;
  valueZero: number;
}

After this change, the models are generated as:

export interface BooleanConst {
  value: true;
  valueFalse: false;
  valueNullable: BooleanConstValueNullable;
}

export interface IntegerConst {
  value: 1;
  valueNullable: IntegerConstValueNullable;
  valueZero: 0;
}
