Style `--version` command

[DaltonSW]

Description

Not sure if I'm just missing something, but using fang.WithVersion() and then go run . --version prints out without any formatting. Given that everything else I've seen with Fang seems to be styled, I think it would make sense for this to be as well

unfortunately cobra does not have a SetVersionFunc, only a SetVersionTemplate, which in our case is not enough.

to style things, we need to evaluate the terminal profile, and build our styles.

with SetHelpFunc, we can do that only if the user is requesting help.

with SetVersionTemplate, we would need to evaluate that before, which may lead to all sorts of problems, unfortunately.

I'll see if I can PR that feature into Cobra, though.

Ohhh interesting, I gotcha. Didn't think of that as a consideration.

I was already considering doing a PR here after some investigation, happy to also look into it for Cobra if that'd be helpful :)
