feat: add icons for .dom files (Dominossauro framework)

[dominicmonteiro]

Description

Adds icons for Dominossauro .dom files.
Note: the official Dominossauro colors are blue and orange (#05518b, #0773ba, #eadd28), which are somewhat challenging to represent in this style. I’ve chosen a compromise that aligns with the existing icon palette and works well in both light and dark themes — but I’m open to suggestions for better color balance.

Do you have a reference for the Dominossauro language? Is there a website or github project available?

We should definitely simplify the icon a little bit. From my point of view it's a little bit too complex as it has too many small details which are not visible anyways while looking at the icon in a small size.
