Code Review

This PR, automatically generated by Snyk, upgrades react-markdown from v8.0.7 to v9.0.0 to resolve a ReDoS security vulnerability. This is a major version bump that introduces breaking changes. My review highlights the high risk of rendering regressions due to significant changes in the underlying rendering pipeline and dependencies, which will require careful validation by the merging developer.

[gemini-code-assist]

This major version upgrade to react-markdown v9 introduces breaking changes. Based on the updated dependencies in package-lock.json, the rendering pipeline has been significantly altered. For example, prop-types and react-is are no longer direct dependencies, and a new dependency hast-util-to-jsx-runtime has been added, suggesting a switch to a new JSX runtime. These changes carry a high risk of causing rendering regressions for existing markdown content, especially if custom components or styles are used.
