🔧 Fix workflow for Mac building (upload-artifact)

It's turns out that actually upload-artifact@v3 is obsolete so that's why workflow has been failed. Updated to v4, and removed extensions from `name` etiquette in upload-artifacts, ty for going me outside my wrong minds. (`name` of artifacts should not have an extension, otherwise it's a tiny trap btw)
