Renovate Bot Integration in CI

[thekester]

This is a follow-up to PR #581. I originally used branch 572-use-renovate-in-ci to add a Renovate configuration, but the rebase onto dev caused a messy commit history. To fix this, I created a new branch—572-use-renovate-in-ci-v2—directly from the latest dev and added a single commit with the .github/workflows/renovate.yml file. This new branch provides a clean, easy-to-review commit history, effectively replacing the old branch.

Pre-commit hook checks fail (see https://github.com/KhiopsML/khiops/pull/647/checks#step:4:229).

To make sure the checks pass, one needs to:

1. Create Python virtual environment (virtualenv -p path/to/bin/pythonx.y my_virtual_env)
2. Activate the Python virtual environment (. my_virtual_env/bin/activate)
3. Install pre-commit inside the Python virtual environment (pip install -U pre-commit)
4. Run the yamlfix pre-commit hook before doing git add (pre-commit run yamlfix --file .github/workflows/renovate.yml)
   4'. Alternatively, if wishing to automate the run of the pre-commit hooks, one can also:
   • Install the pre-commit hooks (pre-commit install inside the khiops repo / directory)
   • then, each time git commit is attempted, the commit will fail if any pre-commit hook fails.

Thanks, i just did the pre-commit run yamlfix --file .github/workflows/renovate.yml

Technically, LGTM.
However, before being able to merge, IMHO we would need to:

• squash the 2 commits
• Rephrase the commit message of the single remaining commit, to:
