added ceu-3 and eur-11 as predefined values to product

Restriction on products values has been added since, we have no information regarding two other product in Nukleu and on the other hand those two dataset don't have rsds and sfcwind vars.

There is a minor issue in freva-web wich predefined_facet doesn't fucntion well now, but after merging https://github.com/FREVA-CLINT/freva-web/pull/71 we will be able to restrict the product

this is only a PR to make the PET function properly as is now. We have to change the all again after providing the pvap param
