[Global/Quartus2] Remove template

The template hasn't been touched since it was introduced here. There are some problems with it - mainly that it's hard to know if these rules are all still relevant, and the large prose block is probably more confusing than helpful here.

I searched for some phrases from the comments and found that the template is only used in a handful of repositories, and these are almost all one-off coursework projects which were used briefly and then abandoned. Since this is unmaintained and seems to be a bit of a niche tool, it's probably not a good fit for this collection. I'll leave this open for a while in case anyone objects.
