fix(node): set default http server response code 200 (#23977)

Node sets the default HTTP response status code to 200 on the
`ServerResponse`. We initialised it as `undefined` before which caused a
problem with 11ty's dev server.

Thanks to @vrugtehagel for reporting this issue and finding the correct
fix as well 🎉
