* fix: add file extention when the absolute path to the runtime files are used (#12824)
the es module imports need the file extention (e.g. import "@babel/runtime/helpers/jsx.js", Or the filenames being listed in the package.json's subpath exports (e.g. "import "@babel/runtime/helpers/jsx" + pkg: "./helpers/jsx": "./helpers/jsx.js"). when the user passes a path via `absoluteRuntime` then the rendered require staemnts is not the module name + subpath which will be resolved via pkg.json but rather the absolute path to the file. for this case, add the file extention / index.js to prevent bundlers from raising a warning.
* Update deps
* Fix imports resolution
* Update fixtures (Windows)
