Support for GCC14 & GCC15 in the cpp images

[gldraphael]

It would be very nice if we could specify a GCC version for the existing images similar to how we can currently specify a CMAKE version. But just having access to only the latest GCC would be nice too, since many of the newer C++ features (like println from the print header) are not supported in GCC13.

Thank you for the feedback! I wonder if @sinemakinci1 has any thoughts on this? :)

@gldraphael @bamurtaugh Thanks for forwarding, I think this is a very valid request if feasible, as there are some C++ features that require min GCC 14 or 15 to be able to compile (see: https://en.cppreference.com/w/cpp/compiler_support/23)!

Thanks so much for the feedback!
