What problem does this feature solve?

https://rspress.dev/plugin/official-plugins/api-docgen#apiparsetool

1. Maintainability, react-docgen is the officital tooling to generate type doc of react component in Facebook, and the last-update of react-docgen-typescript is 2021

2. More features, analyze nested types and generate documents of nested types, and we can use the playground for better debugging of component-document

What does the proposed API look like?

https://rspress.dev/plugin/official-plugins/api-docgen#apiparsetool

1. use apiParseTool option react-docgen to switch from react-docgen-typescript to react-docgen
2. We hope to switch the default value of apiParseTool to react-docgen in Rspress 2.0 and generate the component document for our new member of Rstack, Rslib XD
