repl: fix `NO_COLORS` env var is ignored
refs: https://github.com/nodejs/node/pull/48034#issuecomment-1904710409
the logic in options.useColors = shouldColorize(options.output) || process.env.NODE_DISABLE_COLORS === undefined;
indroduced this bug since shouldColorize
already checks NODE_DISABLE_COLORS
among other env vars that disable colors: NO_COLOR
and TERM === 'dumb'
