Add M4 Mac Mini 1.5U Mount with 1x LabStack Module

> @GarnetSunset single or dual M4 Mac Mini 10inch rack would be amazing, probably 3D printed to save on cost!

> For a 3D printed mount, it would end up being closer to 1.5U rather than the 1.25U of that mount, just to make sure there's enough material for the weight of the Mac Mini, and for a 10" rack, you wouldn't be able to get more than one Mac Mini.
>
> The total opening width on the 10" rack is ~222mm (8.75"), and each M4 Mac Mini is 127mm (https://www.apple.com/mac-mini/specs/).

> Thinking out loud, I could probably make a 1.5U mount for the M4 Mac Mini, plus a single LabStack module on its side, and MAYBE a keystone jack for the MacMini's Ethernet port and/or HDMI port. I could DEFINITELY make a 2U version, but would still only be able to add a single LabStack module, but it would allow multiple keystone jacks for the Mac Mini...

> Let me know if there's interest, and I'll see about adding it to my list for LabStack modules (so long as Jeff doesn't mind the hijack).

首先查看现有的 LabStack 安装支架设计和链接的 19-inch Mac Mini 参考设计，然后将它们与本 issue 中的 10-inch 机架尺寸进行比较。完成的标准是确定一个 1.5U 3D 打印安装支架，能够容纳一个 M4 Mac Mini 和一个 LabStack 模块，并解决所有 keystone-jack 选项。
