Example on adding color styles to --help?

[shusso]

Tried to search the docs and examples for a simple example on how to add color styles to the --help output. I found this comment from an issue which was what I was looking for
#3234 (comment)

Would it be beneficial to add color styling example to examples?

Command::styles has an example for how to use it.

FYI clap's default terminal styling (colors) is being revisited in #5881.
