435 get khiops version among extra info

[tramora]

Fixes #435

When putting debugging extra info, khiops core does not use a OS specific line separator but always a Unix separator.
Because of this khiops-python couldn't get correctly the version on Windows.

TODO Before Asking for a Review

• Rebase your branch to the latest version of dev (or main for release PRs)
• Make sure all CI workflows are green
• When adding a public feature/fix: Update the Unreleased section of CHANGELOG.md (no date)
• Self-Review: Review "Files Changed" tab and fix any problems you find
• API Docs (only if there are changes in docstrings, rst files or samples):
  • Check the docs build without warning: see the log of the API Docs workflow
  • Check that your changes render well in HTML: download the API Docs artifact and open index.html
  • If there are any problems it is faster to iterate by building locally the API Docs
