Automation of production files

[blubbsy]

This creates a github action that automatizes the generation of 3D Render, gerber files, BOM, etc. my intention is to find errors automatically over time by continuing improving the KiBOT implementation. At the same time when it comes to releases the artifact files could be used for it.

The action is only triggered manually or when a pull request is done.

• Changed name of inner layers from InN --> InnerN
• Created github action
• Added Kibot yaml for every pcb
• DRC checks (not checked tbh)

I think it is a good base for automatically check for errors and create the necessary files without bigger errors. At least assuming in KiCAD everything is done properly.

I noticed already that the 3D models are not all included in the project, so this is something that can be worked on too.
