Describe the bug

I have a specific setting in my .swiftlint.yml to exclude function declarations

line_length:
  warning: 120
  error: 200
  ignores_function_declarations: true

However, this ignores the macro definitions

// Line Length Violation: Line should be 120 characters or less; currently it has 126 characters (line_length)
@freestanding(expression)
public macro obfuscate(_ value: String) -> String = #externalMacro(module: "ObfuscatedStringMacros", type: "ObfuscationMacro")

Complete output when running SwiftLint, including the stack trace and command used

$ swiftlint lint

Gives me

Line Length Violation: Line should be 120 characters or less; currently it has 126 characters (line_length)

Environment

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

disabled_rules:
  - todo
  - trailing_comma
  - trailing_whitespace
opt_in_rules:
  - empty_count
line_length:
  warning: 120
  error: 200
  ignores_comments: true
  ignores_function_declarations: true
  ignores_interpolated_strings: true
  ignores_urls: true

• Are you using nested configurations?
  If so, paste their relative paths and respective contents.
  No
• Which Xcode version are you using (check xcodebuild -version)?
  Xcode 15.4
• 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.
  Create a macro using Xcode and run the linter to recreate the issue

// This triggers a violation:
@freestanding(expression)
public macro obfuscate(_ value: String) -> String = #externalMacro(module: "ObfuscatedStringMacros", type: "ObfuscationMacro")
