// Parameters:
//   - cmd: The Cobra command to add the format flag to
//   - converterType: Pointer to the ConversionFormat variable that will store the flag value
//   - bindViper: If true, binds the flag to viper for configuration file support.
//     Set to true for commands that use viper for configuration (e.g., watch command),
//     and false for commands that don't (e.g., optimize command).
