doc: fix typo in cjs example of util.styleText

[deokjinkim]

errorMessage needs to be printed instead of successMessage in console.error().
ESM example is only fixed in previous PR.

Refs: #56720

Thanks @deokjinkim for creating this PR, but we just recently landed #56720.

@UlisesGascon As I mentioned in PR description, only ESM example is fixed in #56720 like below: (line 1975)

node/doc/api/util.md

Lines 1969 to 1975 in ce6a628

	const errorMessage = styleText(
	'red',
	'Error! Error!',
	// Validate if process.stderr has TTY
	{ stream: stderr },
	);
	console.error(errorMessage);

CJS example is not fixed yet(line 1991). So I created this PR.

node/doc/api/util.md

Lines 1985 to 1991 in ce6a628

	const errorMessage = styleText(
	'red',
	'Error! Error!',
	// Validate if process.stderr has TTY
	{ stream: stderr },
	);
	console.error(successMessage);

You are right! Sorry for the early closing 😅
