No fucks given

I'll write a custom rule for this after work today for my own system, I'm more just checking if anyone else wants a copy when I'm done.

Research direction
The issue requests a new rule in thefuck to correct the command `figlet moo | cowsay` by adding the ` n` flag. To implement, study existing rules in the `thefuck/rules/` directory, create a Python function that matches the command pattern, and returns the corrected command. Add tests following the project's testing conventions. No linked PRs or complex dependencies exist.
