Subject: fix(node/tty): fix `tty.WriteStream.hasColor` with different args
 (#25094)

The check in `tty.WriteStream.prototype.hasColors()` was incorrect
leading to the
[`yoctocolors`](https://github.com/sindresorhus/yoctocolors) package not
printing any colors.

Fixes https://github.com/denoland/deno/issues/24407
