MHPUS102-19-23-S belt holes too small for BCB5-6 #3

This is a bug in the y carrier belt assembly. The holes on both sides of the 23 link cable carrier (MHPUS102-19-23-S) are 4mm. This is too small for the BCB5-6 bolts indicated in the beta build instructions, cad model and BOM.

I checked misumi. They don't seem to have hntpz5-4 t-slot nuts (with lock), only hntp5-4 ones without lock. I'm not experienced enough to know if either drilling or hntp5-4 will work best for this application.

In any case, some additional documentation is needed. I would gladly update this myself, but I don't know where I could. I have no better place to mention this than a github issue :-(

Noted. We are working on building instructions that can take better feedback.

I recommend drilling it to make it work with an m5 screw.
