I just realised there are other jobs below in the file, can't they be fused with the one you added here, just by include-ing more elements to the matrix? It'd make the file a lot shorter, and avoid duplication everywhere

Thanks @giordano the JRA55 tests pass, the Reactant tests do not pass still because of the issue in Oceananigans. I ll start merging this.
