What's Changed

• Allow MDX stories ending with stories.mdx or story.mdx by @IanVS in https://github.com/storybookjs/builder-vite/pull/337
• Prevent FOUC in the iframe while loading by @IanVS in https://github.com/storybookjs/builder-vite/pull/339
• react-docgen: exclude node_modules, make configurable by @IanVS in https://github.com/storybookjs/builder-vite/pull/338

React projects without typescript, or typescript react projects choosing to use react-docgen may see a performance improvement in this release due to no longer processing files in node_modules with docgen. If you need to customize which files are processed, see https://github.com/storybookjs/builder-vite/pull/338 for an example.
