Bindings to React modules are incompatible with node ESM

[bloodyowl]

hello 👋

great work on the release!

I just found out that the new bindings, omitting the .js extension break when using node in ESM mode, as it tries to resolve to .mjs when unspecified. It currently breaks ReScript Pages (https://github.com/bloodyowl/rescript-pages/tree/upgrade-rescript-react) at runtime with the following error:

Error [ERR_MODULE_NOT_FOUND]: Cannot find module '/Volumes/Dev/bloodyowl/rescript-pages/node_modules/react/jsx-runtime' imported from /Volumes/Dev/bloodyowl/rescript-pages/src/PagesServer.mjs
Did you mean to import react/jsx-runtime.js?

    at link (node:internal/modules/esm/module_job:75:36) {
  code: 'ERR_MODULE_NOT_FOUND'
}

and will most likely break any project in this configuration.

would you consider a PR adding the extensions back into the declarations?
