Curtin install_grub.py not fully updated for RHEL 10

I noticed that the update to curtin that added support for RHEL 10 missed a line:

curtin/commands/install_grub.py

79d9f17d4


      
          def gen_install_commands(grub_name, grub_cmd, distroinfo, devices,
                                   rhel_ver=None):
              install_cmds = []
              post_cmds = []
              if distroinfo.family == distro.DISTROS.debian:
                  install_cmds.append(['dpkg-reconfigure', grub_name])
                  install_cmds.append(['update-grub'])
              elif distroinfo.family == distro.DISTROS.suse:
                  post_cmds.append(['grub2-mkconfig', '-o', '/boot/grub2/grub.cfg'])
              elif distroinfo.family == distro.DISTROS.redhat:
                  if rhel_ver in ["7", "8", "9"]:
                      post_cmds.append(
                          ['grub2-mkconfig', '-o', '/boot/grub2/grub.cfg'])
                  else:
                      raise ValueError('Unsupported "rhel_ver" value: %s' % rhel_ver)
              else:
                  raise ValueError("Unsupported os family for grub "
                                   "install: %s" % distroinfo.family)
              for dev in devices:
                  install_cmds.append([grub_cmd, dev])

So it is failing for me when I try to install to a proxmox vm via maas.
Hopefully that can get a quick fix.
