[macOS] fix c++23 issue using make

[dimitre]

closes #8111

[danoli3]

Still confusing since c++23 is available in Xcode 15.

Did you make sure you have run xcode-select --install

[danoli3]

sudo softwareupdate --all --install --force

[dimitre]

I've run it again by editing config.make

export MAC_OS_CPP_VER = -std=c++23

and the full error is

error: error: invalid value 'c++23' in '-std=c++23'

[dimitre]

so maybe c++2b is the parameter you want to enable 'Working draft for ISO C++ 2023 DIS' standard

[danoli3]

Yeah 2B I used originally not sure why it changed to 23! I think maybe when had some issues with windows using that

it was hard to debug because platform templates were overriding with c++17
and in some cases when we use "vscode" and "osx" templates it copies config.make twice, so the last added template will count.
