SPM plugin: Mac Catalyst build fails

New Issue Checklist

• Updated SwiftLint to the latest version
• I searched for existing GitHub issues

Describe the bug

My small lib PDefaults uses SwiftLint as a SPM plugin.

It won't build using XCode 14.3.1 with My Mac (Mac Catalyst) run destination.

It's in fact SourceKitten that's failing.

caused by this snippet, the compiler considering canImport(Darwin) is true:

            if #available(macOS 10.13, *) {
                process.executableURL = URL(fileURLWithPath: command)

Environment

• SwiftLint version (run swiftlint version to be sure)? 0.52.3
• Installation method used (Homebrew, CocoaPods, building from source, etc)? SPM plugin
• Paste your configuration file: not relevant
• Are you using nested configurations? not relevant
• Which Xcode version are you using (check xcodebuild -version)? 14.3.1
• Do you have a sample that shows the issue?

• Create a dummy package with SwiftLint used as a plugin like this:

import PackageDescription

let package = Package(
    name: "PDefaults",
    platforms: [
        .macOS(.v12),
        .iOS(.v13)
    ],
    products: [
        .library(
            name: "PDefaults",
            targets: ["PDefaults"]
        ),
    ],
    dependencies: [
        .package(url: "https://github.com/realm/SwiftLint", exact: "0.52.3")
    ],
    targets: [
        .target(
            name: "PDefaults",
            dependencies: [],
            plugins: [.plugin(name: "SwiftLintPlugin", package: "SwiftLint")]
        ),
    ]
)

• try to build it for Mac Catalyst with XCode 14.3.1

Start with SourceKitten's Source/SourceKittenFramework/Exec.swift, especially the Process setup shown in the report, and reproduce the failure using the provided PDefaults package with SwiftLint 0.52.3 on a Mac Catalyst destination in Xcode 14.3.1. Done means the sample package builds for Mac Catalyst without the reported Process availability and ambiguous launch errors.
