Bumps [ray](https://github.com/ray-project/ray) from 2.44.0 to 2.52.1. <details> <summary>Release notes</summary> <p><em>Sourced from <a href="https://github.com/ray-project/ray/releases";>ray's releases</a>.</em></p> <blockquote> <h2>Ray-2.52.1</h2> <ul> <li>More robust handling for CVE-2025-62593: test for more browser-specific headers in dashboard browser rejection logic</li> </ul> <h2>Ray-2.52.0</h2> <h1>Release Highlights</h1> <p><strong>Ray Core:</strong></p> <ul> <li>End of Life for Python 3.9 Support: Ray will no longer be releasing Python 3.9 wheels from now on.</li> <li>Token authentication: Ray now supports built-in token authentication across all components including the dashboard, CLI, API clients, and internal services. This provides an additional layer of security for production deployments to reduce the risk of unauthorized code execution. Token authentication is initially off by default.
