In pxegrub2_chainload.erb various paths are tried, but the /EFI/rocky/grubx64.efi path is missing. This causes the server to refuse to boot.

I verified this with foreman-3.4.0-0.3.develop.20220623140235git143054a.el8.noarch and provisioned a Rocky Linux 8.6 server using a libvirt VM using UEFI.

Initially this was reported as an installer problem in #35101 but I don't believe this is the case.
