[Keith Smiley via llvm-commits]

https://github.com/keith created https://github.com/llvm/llvm-project/pull/105993

Virtual environments in python 3.12 no longer installs setuptools by default in order to push people towards newer syntax for installing packages. This new syntax is also compatible with python 3.8 which is the current lowest supported version mentioned in the docs.
