The "Options" section will always have rich formatting enabled

[sounisi5011]

I'm using clipanion@3.2.0-rc.4.
In testing my CLI using clipanion, I tried to use the environment variables NO_COLOR and FORCE_COLOR to force disabling color output. However, only the "Options" section was not in text format.

The reason for this is that only the "Options" section uses the richFormat.header() method directly.

clipanion/sources/advanced/Cli.ts

Lines 532 to 535 in 488cfd0

	if (options.length > 0) {
	result += `\n`;
	result += `${richFormat.header(`Options`)}\n`;

I think this is a bug because all the other sections use the this.format(colored).header() method.
