fix: gradle warning color

[m1ga]

Will show the gradle warnings as warnings and not as errors:

LGTM

I accidentally merged #611 too quickly and reverted it in #612.

The correct place to fix the Gradle warning is in the createReadableDataHandlerUsing() function: https://github.com/tidev/titanium_mobile/blob/master/android/cli/lib/gradle-wrapper.js#L178-L204

Fixing this isn't too hard. The code directs all Gradle stdout to this._logger.info and all stderr to this._logger.error. I recommend passing this._logger into createReadableDataHandlerUsing() (or use an arrow function) and also pass in a string with 'stdout' or 'stderr' (or use 1 and 2 like the file descriptor number). Then in that function do:

for (const nextMessage of messageArray) {
    let logMethod = fd === 'stdout' ? 'info' : nextMessage.includes('Warning') ? 'warn' : 'error';
    this._logger[logMethod]('[GRADLE] ' + nextMessage.replace(/\r/g, ''));
}

This certainly could be cleaned up.

works fine: tidev/titanium-sdk#13694
I've used the string parameter and pass in "error" or "info"
