Missing Drill Layer in Trackball PCB gerber file

[ya-luotao]

Thank you so much for sharing this fantastic open-source keyboard project! I really appreciate all the hard work and dedication you’ve put into creating and sharing this.

I recently used the provided gerber files to order PCBs in JLCPCB and building Keyball39 , but unfortunately, I encountered an issue. It seems that the gerber file of Trackball PCB is missing the drill layer. Would you have a chance to take a look?

Thanks again for this project and your time!
