/// The `$command` must impl `LprsCommand` trait

/// ### Example:
/// ```rust
/// create_commands!(

///     Test Some
/// );
/// ```
/// #### Output
/// ```rust

///     fn run(&self, vault_manager: crate::vault::Vaults) -> crate::LprsResult<()> {
///         match self {
///             Self::Test(command) => command.run(vault_manager),
///             Self::Some(command) => command.run(vault_manager),
///         }
///     }
///
///     fn validate_args(&self) -> crate::LprsResult<()> {
