homebrew-chef update script only handles intel packages

[tas50]

In the legacy homebrew repo at https://github.com/chef/homebrew-chef we have a script to update the configs https://github.com/chef/homebrew-chef/blob/main/.expeditor/update_version.sh which currently only handles the intel side of things. This needs to get updated to handle both intel and arm. The inspec, infra client, and workstation definitions all have arm packages so the logic here should be set to update all 3 of those configs. DK is legacy and will never get updated again so nothing to worry about there.

@tas50, i only see chef-workstation in brew.sh. Where do we find the others such as Chef Infra Client, Chef InSpec?
