fix: 🐛 Fix intel macs not getting proper auto-update prompt

[ZedLi]

Description

Fixes an issue we were seeing where intel macs weren't properly getting auto-updated. We were returning x64 instead of amd64 and being unable to find the URL because of that.

Screenshots (if appropriate)

How to Test

Creating a build here and will test on our mac instance.
