I hadn't thought about this before. But this is breaking if someone was using the automatic download of Gurobi on linux, and they update their package version without updating their license. This is probably okay for now, because we shouldn't have too many people affected and it's a simple change.

But longer term, I wonder about syncing the major version of Gurobi.jl with Gurobi, so this would become v11.0.0. The downside is then we'd only ever support the latest major version, unless we back ported fixes to Gurobi.jl v10.X.Y.

I also missed the fallback path for the artifact in the library loader. That's updated now, so I think things are working as expected this time.

Confirm that I see Gurobi Optimizer version 11.0.0 build v11.0.0rc2 (linux64 - "Ubuntu 22.04.3 LTS")
