/// Creates commands macro, to create the `Commands` enum and impl `RunCommand` to it.
///
/// ### Notes:
/// The `$command` must impl `RunCommand` trait
///
/// ### Example:
/// ```rust
/// create_commands!(
/// enum TestCommands
/// "Test command", Test => TestArgs
/// "Do something", Some => SomeArgs
/// );
/// ```
/// #### Output
/// ```rust
/// ///The lprs commands
/// pub enum TestCommands {
/// ///Test command
/// Test(TestArgs),
/// ///Do something
/// Some(SomeArgs),
/// }
///
/// impl crate::RunCommand for TestCommands {
/// fn run(
/// &self,
/// password_manager: crate::password::Passwords,
/// ) -> crate::LprsResult<()> {
/// match self {
/// Self::Test(command) => command.run(password_manager),
/// Self::Some(command) => command.run(password_manager),
/// }
/// }
/// }
/// ```
