minimized cloud image policy, introduced in version 23.10.16, is to not install recommends for any package installs during build. This is to keep the image as small as possible. This also extends to the grub related packages. This solves the problems detailed in LP: #2037075 and aligns other arches more with amd64 install of grub/shim packages for both minimized and non minimized ubuntu-cpc cloud image builds.
