[bug] toggle_bool false positive

[rogerluan]

New Issue Checklist

• Updated SwiftLint to the latest version - I honestly didn't and I'm on v0.39.2 but I believe this still happens in latest version (can't upgrade to test right now 😿 ) - feel free to close if you're able to test it and it doesn't happen in the latest release 🙏
• I searched for existing GitHub issues

Describe the bug

toggle_bool false positive.

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

$ swiftlint lint

Environment

• SwiftLint version (run swiftlint version to be sure)? 0.39.2
• Installation method used (Homebrew, CocoaPods, building from source, etc)? Homebrew
• Paste your configuration file:

# The only relevant part is:

opt_in_rules:
  - toggle_bool

• Are you using nested configurations?
  If so, paste their relative paths and respective contents. 🤔 don't think so
• Which Xcode version are you using (check xcodebuild -version)? Xcode 12.0
• 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.

This shows my issue:

echo "something = \!something.isEmpty ? executeA() : executeB()" | swiftlint lint --no-cache --use-stdin --enable-all-rules

There is a \ before the ! to escape the ! because apparently that causes issues in the script. But the example in Swift would be:

// This triggers a violation:
something = !something.isEmpty ? executeA() : executeB()

And it shouldn't. In my project the line was much more complex but I could simplify and reproduce it using that statement. In my project I just switched the ternary to e.g. something.isEmpty ? executeB() : executeA() but not sure if that will be possible in all cases 🤔

I can confirm that this is still a false positive present on master.
