chore: remove colors & ANSI characters.

  owo-colors has proven to be quite a pain to work with inside Aiken. So at this point, I am not sure we want to commit yet to using it. So I've simplified the panic hook to be less fancy looking, but still provide the valuable information. We can re-assess later whether and how we can to make it prettier.
