[SCIP] SCIP with AMPL bindings (scipampl.exe) for Windows in download section?

[Stefan Vigerske]

Hi,

I don't think we want to start building SCIP/AMPL executables for old 
SCIP releases where there aren't available so far. Just build from 
source, if you need that.

Since SCIP 8.0, the AMPL bindings are part of the main SCIP. Thus, the 
downloads of scip.exe for all releases since 8.0.0 should be usable in 
Pyomo.

The move of the AMPL bindings into main SCIP is also mentioned in the 
changelog and the release report and came up repeatedly on this mailing 
list.

Nonetheless, it took me a while digging into different questions on stackoverflow, to figure out that the conventional "scip.exe" from the installer does not work with Pyomo's SolverFactory (https://pyomo.readthedocs.io/en/stable/solving_pyomo_models.html) and I had to use "scipampl.exe" instead.
