Default to --nocolor when piping output from ansible-lint

[unikitty37]

The issue tracker requires pasting the output from ansible-lint --version into the template. As macOS has the pbcopy command, which copies piped input to the pasteboard, I naturally tried ansible-lint --version | pbcopy, but I got this:

ansible-lint �[1;36m6.21.1�[0m using�[2m ansible-core:�[0m�[1;2;36m2.15.5�[0m�[2m ansible-compat:�[0m�[1;2;36m4.1.10�[0m�[2m ruamel-yaml:�[0m�[1;2;36m0.17.39�[0m�[2m ruamel-yaml-clib:�[0m�[1;2;36m0.2.8�[0m

I figured the devs wouldn't particularly appreciate that 😁 so ended up using ansible-lint --version and copying the output with the mouse, like an animal. I later discovered the --nocolor flag.

However, it would be much more helpful if the default behaviour with no colour flags or variables set was to have colour on, except when the output is being piped.

(Actually, I'm not sure if this is a bug — the presence of the --force-color flag implies that this might be the intended behaviour…)
