Cannot Downlad STEP file for Hinge Tutorial

[JiffyRob]

I was working through the hinge tutorial and found that there wasn't any builtin way to download the STEP file for the countersunk screw (https://github.com/gumyr/build123d/blob/dev/docs/M6-1x12-countersunk-screw.step) off of the docs website. I managed to pull it from the link above, but it ought to be able to be downloaded from the docs.
