ARM64 version of Hugo not installed on Apple silicon Mac

[dboulet]

When using this package to install Hugo on a Mac with Apple silicon, the AMD64 version is installed instead of the ARM64 version which is built for Apple processors. This is because the arch package that this package ultimately depends on doesn’t properly detect ARM64 architecture on Apple silicon Macs, and reports it as being x64.

There is a pull request to fix this issue: https://github.com/feross/arch/pull/22.
