Overall great work. Just a few comments about the scaling and color of the plain svg.

@canaleal Thanks for the review! Just pushed an update with the SVGs updated to reach the edge of the fillbox. Note: the icon is not square, it is a rectangle whose longest dimension is the height. The Y dimension reached the edge of the fillbox, but the X dimension does not.

Also updated the plain icon color to match the primary color in devicon.json.
