HelpProvider colors should be configurable

The colors in the HelpProvider are hardcoded. Showing help on a bright background (e.g. old school default MacOS terminal) becomes really hard to read, primarily because of the yellow colors.

How do I deal with that? I can create a custom help provider, but that seems a bit much just to fix some hardcoded colors.

FYI. I'm actively working on this.

The latest check-in on the draft PR, now supports removing all styling from the help text through a configuration setting, namely:

configurator.Settings.IgnoreStyling = true;

At the moment, the default remains false, preserving the current default behaviour to style help text.

FYI. I've checked in a PR with the final proposed changes, ready for review. #1408
