What kind of change does this PR introduce?
Bug fix
What is the current behavior?
Due to the recently merged PR https://github.com/powsybl/powsybl-open-rao/pull/1070, the relative ranges for PST in 2P Global Optimization (when modeled as APPROXIMATED_INTEGERS) were no longer respected.
This made the test 19.11.9.bis fail when ran with XPRESS.
What is the new behavior (if this is a feature change)?
I've changed the MIP equation and now they are.
