An internal heuristic needs to be updated

Description

Vite-plugin-ssr uses an internal heuristic to detect whether you are using React.

This heuristic may change over time.

If you run into the warning [vite-plugin-ssr][Warning] An internal heuristic needs to be updated then help us update the heuristic by doing the following:

1. Update vite-plugin-ssr to its latest version ($ npm info vite-plugin-ssr).
2. Edit node_modules/vite-plugin-ssr/dist/esm/utils/detectHydrationSkipSupport.js and add a new line:

   console.log(`isReact1: ${isReact1}, isReact2: ${isReact2}, isReact3: ${isReact3}`);
   

   Just before this line:

   assertWarning(condition, 'An internal heuristic needs to be updated...');
   

3. rm -rf node_modules/.vite/ then start your server and let us know the output of the console.log() you just added.
4. What UI framework are you using? Which version? If you use React:
   • $ cat node_modules/react/package.json | grep version
   • $ cat node_modules/@vitejs/plugin-react/package.json | grep version

FYI, this heuristic is only used to set the right default boolean value of an option. This heuristic is not crucial and can be removed. (Removing it would only induce a slight DX inconvenience as the user would have to manually set the option’s value).

Updated heuristic released in v0.4.28. I didn’t test the change but I believe it should work. Let me know if you still get the warning.
