Describe the feature you'd like

Currently, the knowledge base does not support uploading files with the .mdx extension. It would be helpful if Ragflow could add support for MDX file uploads, allowing users to seamlessly upload and integrate MDX files into their knowledge base.

Use Case: • MDX files are commonly used for combining Markdown with React components, and enabling support for them would expand the types of content users can manage within Ragflow. • This feature would be beneficial for teams or developers who prefer to use MDX for content creation due to its ability to embed dynamic components within Markdown.
