I don't know if that entry is correct, but assume it should be ok, then
you still need to update /boot/grub/grub.cfg. There is a command [1]
that will generate a new grub.cfg based on the OS prober thingy and the
config you edited.

Perhaps the command is

  sudo update-grub

"The menu list of available Linux kernels is automatically generated by
running update-grub." - https://help.ubuntu.com/community/Grub2

As already mentioned, I edit grub.cfg manually and don't use all this
automation thingies.
