Let it make more universal

Hi, useful extension, thx... but some ideas:
1. `<?= \Yii::t('skeeks/cms', 'Add'); ?>` - not all project use skeeks cms, if you use clear yii2 you will get error: Unable to locate message source for category 'skeeks/cms'.
2. Please don't use Short Tags `'<?' `by default is disabled, and from PHP7.4 is deprecate, in PHP 8 will be removed
