This PR merges the latest changes from the upstream repository jaywhj/mkdocs-document-dates into our branch. It resolves several merge conflicts in the core logic and project configuration while ensuring our custom improvements (like timezone normalization and HTML escaping) are preserved. Additionally, it synchronizes the documentation assets and files from upstream and organizes them into a multi-language setup with a landing page, avoiding direct conflicts in the future.
