/// A macro to execute an uninstall 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, version, and client, and
/// then uninstalls the package.
///
/// # Parameters
///
/// - `$command`: The command to be matched and executed. The command must
///   include a `version`.
/// - `$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.
