fix(color): no color for non-tty

[wass3r]

fixes go-vela/community#1056

avoids issues when you have color output enabled but are sending output to non-terminal. example (typically, the scenario is that you might have color enabled globally):

$ vela --color true view repo --org <org> --repo <repo> --output json | jq -r '.'

currently results in:

jq: parse error: Invalid numeric literal at line 1, column 2

due to color codes in response. this simple fix in the PR overrides color output in such scenarios so users don't have to manually strip color code prior to working with the data when piping to other utils.

I'm desperately wanting this today as my team will have a need to list secrets a lot in the next couple of weeks as we do a minor refactor of our Vela config as we migrate ~120 repos to a new directory layout, among other things.
