Trying out this new compat CI thing..

As I understand, we should bump Nemo.jl versions to 0.32-0.38 in StructuralIdentifiability.jl ?

https://github.com/SciML/StructuralIdentifiability.jl/actions/runs/7167680162/job/19514247808#step:5:44

At the moment, ParamPunPam.jl restricts Nemo.jl to 0.32-0.37, and StructuralIdentifiability.jl restricts Nemo.jl to 0.24-0.38. Hence, the lowest possible bound is 0.32

Yes, I agree 0.32 looks like the lowest feasible

Note for future self: make sure that Groebner.jl v0.6.1 supports Nemo.jl v0.39 (currently v0.6.0 does not https://github.com/sumiya11/Groebner.jl/blob/v0.6.0/Project.toml)

In the light of https://github.com/SciML/StructuralIdentifiability.jl/pull/260

@pogudingleb thanks for fixing this! I also have this check in Groebner.jl now
