Thank you! Could you also add it to https://github.com/babel/website/blob/main/docs/plugin-transform-react-jsx-development.md#options and https://github.com/babel/website/blob/main/docs/preset-react.md#options? It should be gated by |

Per JLHwung's review, the developmentSourceSelf option is only accepted by the development plugin, not the main plugin-transform-react-jsx. Move the option docs to plugin-transform-react-jsx-development.md, above the 'see options in' sentence.

Adds a migration note for the new
developmentSourceSelfoption introduced in babel/babel#17845.React 19.2 removed the
sourceandselfparameters fromjsxDEV. Babel 8 no longer generates them by default in development mode. Users on older React versions can opt back in withdevelopmentSourceSelf: true.
