does it work with a recent OpenSSL 3.x? as 1.x is already EOL

I can build locally using OpenSSL 3.5.0 (latest). Addressed the changes on the commit 07ed7e8

@jcar87 The Python 3.12.7 is available in the PATH, and is installed in /opt/pyenv/versions/3.12.7/bin. It did not change the Python 3.7, the 3.7 remains the main version. |

Having Python 3.12 is important to run internal tools in the CI, but as Conan should be working with an older version, both Python versions can be installed in parallel in the image.
The OpenSSL 1.1 is required in order to build Python 3.12: https://github.com/pyenv/pyenv/wiki/Common-build-problems#2-your-openssl-version-is-incompatible-with-the-python-version-youre-trying-to-install; Ubuntu 16.04 only offers OpenSSL 1.0, so we need to build it from source.
UPDATE: OpenSSL 3.x is compatible and will be used instead of 1.1.x version.
