Code Review

This pull request adds a language selector to the README.md file, providing links to translated versions of the documentation. This is a helpful addition for international users. My review includes a fix for a malformed HTML tag that could affect rendering, and a suggestion to use modern HTML attributes for consistency and correctness. With these changes, the new feature will be well-integrated.
