Notes

I've also fixed a problem with adobe spark which was overwritten by apache spark because they had the same base name.

• [X] If the icon has light and dark, verified the auto switch works correctly
• [x] The Svg does not contain any sort of strokes

my implementation of the #225 contains strokes, this is why I'm not pushing it right now... but it kinda hard (more time consuming whise) to make a version without strokes.

I think I'm going to just take the jax icon out and work on it another time, I don't really have the time to work on making an icon from scratch right now... If someone wanna work on it, they can. no worries @triilman25
