How it works?
Global Configuration:
First, we get a code of actual used language and on it we base our conditional statement for setting tooltip description.
Descriptions are stored in local array.
For each language translation is needed - currently I have only English descriptions(default) . OR we could use only English descriptions, but I preferred prepare the ground for translations - it's better for non-English/poor-English speaking users from countries which languages we're supporting.
Create Saving Product: there tooltips were already implemented, but in HTML-side ( {{ label.something.description | translate }} ) but not every language have translation.
