Subject: [PATCH 1/2] util: allow color aliases in styleText

Fixes an issue where `util.styleText()` would throw an error for
valid color aliases like 'grey' in Node.js >= 25.7.0. It now uses
`ObjectGetOwnPropertyNames` instead of `ObjectKeys` to fetch both
keys and aliases.

Fixes: https://github.com/nodejs/node/issues/62177
