cli: strip ansi from stderr if no support

[davidjgoss]

🤔 What's changed?

• For the publish banner, check the colors support of stderr and adjust what we output accordingly
• For the reports server output, check the colors support of stderr and strip ANSI escapes from the output if necessary

⚡️ What's your motivation?

Fixes #1698.

For stdout, this should be adequately covered by the changes in #2026. Also, there are known cases for users wanting to keep ANSI escapes from formatter output even though the stdout stream doesn't support displaying them (e.g. writing output to a file store and then streaming the contents back to the client application separately) which are also handled there.

🏷️ What kind of change is this?

• 🐛 Bug fix (non-breaking change which fixes a defect)
