Nuxeo Retention uses superseded config value

Nuxeo retention uses `nuxeo.retention.compliance.enabled` when it should use `nuxeo.retention.strictmode.enabled` (changed since LTS 2021 HF41).

See:

• 2021: https://github.com/nuxeo/nuxeo-retention/blob/lts-2021/nuxeo-retention-package/src/main/resources/install/templates/retention/nuxeo.defaults
• 2023: https://github.com/nuxeo/nuxeo-retention/blob/lts-2023/nuxeo-retention-package/src/main/resources/install/templates/retention/nuxeo.defaults

Related doc link, but the doc is ok I think: https://doc.nuxeo.com/nxdoc/nuxeo-retention-installation-standard/#setting-the-addon-in-standard-mode
