/// Macro to execute a command based on the provided variant and package type.

/// This macro matches the provided command against a list of command variants
/// and executes the corresponding code for each variant. It creates a new
/// `Package` instance with the specified package type and client, and then
/// lists the package versions.
///
/// # Parameters
///
/// - `$command`: The command to be matched and executed.
/// - `$client`: The client to be used for creating the `Package`.
/// - `$(($variant:ident, $package_type:expr)),*`: A list of tuples containing
///   the command variant and the corresponding package type.
