CompatHelper: bump compat for JuMP to 0.23, (keep existing compat)

[github-actions]

This pull request changes the compat entry for the JuMP package from 0.21 - 0.22 to 0.21 - 0.22, 0.23.
This keeps the compat entries for earlier versions.

Note: I have not tested your package with this new compat entry.
It is your responsibility to make sure that your package tests pass before you merge this pull request.

It seems to me that the blocking comes from a chain of inconsistent package versions. The chain ultimately ends in Reexport, which itself is made inconsistent by DynamicPolynomials, which is a dependency of MultivariatePolynomials and TypedPolynomials, which finally use an old version of MutableArithmetics. I reported that here.

The dependency issues are now all resolved. Now we need to fix the breaking change(s) in the tests.

The test failure is caused by a behavioral change in JuMP v0.22 that was only uncovered now (that JuMP version was held back by other packages before). I asked about that change in jump-dev/JuMP.jl#2894.

The JuMP issue was fixed, but we were advised to not use Rationals with JuMP and also to not use infinite bounds. We should discuss this (but not here).

@mforets: The relevant change here is that I commented out the ICP tests because the package seems to be incompatible now. I suggest to support the new JuMP family instead.
