[0.55.1] False positive on `unused_element` where element and index are used separately in subsequent blocks

New Issue Checklist

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

Describe the bug

The rule should not trigger when the enumerated index and element are used in separate subsequent blocks

Environment

• SwiftLint version (run swiftlint version to be sure)? 0.55.1
• Installation method used (Homebrew, CocoaPods, building from source, etc)? Cocoapods
• Paste your configuration file:

# insert yaml contents here

• Are you using nested configurations? No
  If so, paste their relative paths and respective contents.
• Which Xcode version are you using (check xcodebuild -version)? 15.3
• 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.

protocol Rule {
  func isValid() -> Bool
}

let rules: [Rule] = [rule1, rule2]
let messages = ["msg1", "msg2"]

// This triggers a violation:
rules.enumerated()
    .first { $0.element.isValid() == false }
    .flatMap { messages[$0.offset] }
