Format/Lint plugin always targets all target

[zunda-pixel]

CommandPlugin can only select target listed in Package.products

But developer wants to format/lint all target not listed in Package.products

I deleted the code extracting target from arguments

let package = Package(
  name: "swift-format",
  products: [
    .library(name: "SwiftFormat", targets: ["SwiftFormat"]),
  ]
}
