Translation for hardcoded string components

#### Is your feature request related to a problem? Please describe

My problem is that some components like data picker, table(thing like the "Group by:" string) have hardcoded strings as mention in #2287 for @marek-mihok , so as a brazillian user i need a way to translate the language of that components for my clients.

#### Describe the solution you'd like

Any way to change de strings, even a dict or list for me to ingest in the component and handle the translation.

#### Describe alternatives you've considered

I can't considere any solution cuz i cant make alterations in the font, so just want any way to handle this.

Great work y'all, h2o-wave is amazing.
