Support recent versions of setuptools

[PierreR]

The current requirement forces a version of setuptools below 67.7.3 while the latest version is currently 69.x.y

This makes it very hard to build ansible-builder with nixpkgs from the 23.11 branch which uses as a default setuptools 68.2.2

It would be awesome if newer versions of setuptools (at least up to 68.2.2) could be supported.

FYI I created a currently in-progress pull request for nixpkgs where I just manually removed the upper limit as it worked without any issues.
Is there a reason for this upper bounds or could this just be removed?
