Bump compat for OrdinaryDiffEq v7 / SciMLBase v3 ecosystem (#1195)

All Project.toml files now allow SciMLBase v3, OrdinaryDiffEq v7,
OrdinaryDiffEqTsit5 v2, and DiffEqBase v7. The main ecosystem upgrade
was done in #1194; this PR adds the missing SciMLBase compat entry to
the OptimizationBase test/Project.toml.
