Describe the bug

redundant_objc_attribute false positives after updating 0.49.1->0.50.1

Environment

• SwiftLint version (run swiftlint version to be sure)? 0.50.1
• Installation method used (Homebrew, CocoaPods, building from source, etc)? pre-commit
• Paste your configuration file:

# insert yaml contents here

• Are you using nested configurations?
  If so, paste their relative paths and respective contents. No
• Which Xcode version are you using (check xcodebuild -version)? 14.0.1
• Do you have a sample that shows the issue? Run echo "[string here]" | swiftlint lint --no-cache --use-stdin --enable-all-rules
  to quickly test if your example is really demonstrating the issue. If your example is more
  complex, you can use swiftlint lint --path [file here] --no-cache --enable-all-rules.

@objc public extension Foo {
  // This shouldn't trigger the warning
  @objc enum Bar: Int {
    case bar
  }
  // This will have compiler error without the @objc
  var bar: Bar { .bar }
  // This also triggers a warning and also causes compiler error but a better fix would be to mark other private interfaces @nonobjc
  @objc private enum Baz: Int {
    case baz
  }
  private var baz: Baz { .baz }
}

Missed one more false positive:

@objcMembers public class Foo: NSObject {
  // Can't be used with #selector(...) without @objc annotation
  @objc private func dateChanged(_ sender: UIDatePicker) {
    //
  }
}

Any time frame on this PR being released? I also just updated to the latest SwiftLint and getting all these false positives that get compile errors if you fix the lint issues.
