Added ansys 2024R2

Adding Ansys 2024R2 per several requests (Hamza got one, I got one, Frank got one)

As is Ansys's habit, new acquisitions are thrown in there and "let's hope for the best everything works." Due to this, should we perhaps update the Ansys recipe before merging this? A find for bin directories shows a few more directories than we have on our modules:

$ find . -mindepth 2 -maxdepth 2 -type d -name bin
./Framework/bin
./autodyn/bin
./aisol/bin
./CFX/bin
./SystemCoupling/bin
./fluent/bin
./CFD-Post/bin
./TurboGrid/bin
./CEI/bin
./polyflow/bin
./dpf/bin
./aqwa/bin
./RSM/bin
./fensapice/bin
./ansys/bin
./Icepak/bin

Should we leave it as is, to prevent unintended consequences, or update the PATH to add the missing ones (which is easier said than done, since for some of them the actual bin dir is bin/linux64 or whatever.
