[popescu-v]

Checklist (minor release):

• Create branch
• Update CHANGELOG.md
• Push this issue branch and create PR for it
• Merge PR into dev
• Create PR to merge dev into main;
• Merge PR into main;
• Git tag main with 10.2.2.3;
• Push the 10.2.2.3 tag on main; thus, [.github/workflows/pip.yml] and [.github/workflows/conda.yml] are automatically launched on the 10.2.2.3 tag; whence, a GitHub pre-release is created, the Pip packages are pushed to the pre-release, and the Conda packages are pushed to the default khiops-dev channel;
• Launch [.github/workflows/conda.yml] manually, on the 10.2.2.3 tag, selecting the official khiops channel;
• Copy relevant CHANGELOG.md contents to the 10.2.2.3 GitHub pre-release;
• Launch [.github/workflows/api-docs.yml] manually on the 10.2.2.3 tag and instruct it to deploy the documentation pages;
• (After the Conda package has been pushed to the official khiops channel and the API doc has been deployed) Transform the 10.2.2.3 GitHub pre-release into a release.
• Make dev point to the merge commit just created in main. This is necessary to include the merge commit into main to calculate intermediary versions with Versioneer. Steps:

        git switch dev
        git reset --hard main
        git push origin dev # (you need to remove the protections of dev for this step)
