Ubuntu 22.04 is a Tier 1 platform, but main does not build with default gcc, and we do not provide instructions

Cloning the repo and running:

$ ./configure
Node.js configure: Found Python 3.10.12...
WARNING: C++ compiler (CXX=g++, 11.4.0) too old, need g++ 12.2.0 or clang++ 8.0.0
WARNING: warnings were emitted in the configure phase
INFO: configure completed successfully

However, this happens on Ubuntu 22.04.5 LTS, which is a Tier 1 platform. I have not found any instructions in https://github.com/nodejs/node/blob/main/BUILDING.md#unix-prerequisites:

sudo apt-get install python3 g++ make python3-pip

Which installs gcc 11.4.0.

We can't give general instructions for every possible Linux distribution or version of it.

In other words, I think it's fair to assume that the documentation is for the latest version (Ubuntu 24.04 in this case)

It seems interesting to update the configuration script to give some tips on how to update your compiler accordingly on the platform where it is run, instead of saying generic things like need g++ 12.2.0 or clang++ 8.0.0. I have no idea how complex this is, though. If that sounds like a good idea, we can label it as a good first issue and see if someone's happy to take it on.

This is solved with:

sudo apt-get install gcc-12
export CXX=g++-12
./configure

Should be easy to add to the doc, at least for ubuntu.
