Prior to this commit, a change in `HttpStatus.toString` since SPR-16898 prevented the default WebFlux `ErrorWebExceptionHandler` to render template views for exact HTTP status (e.g. "404.html"). This issue does not affect the resolution of series, like "4xx.html". This commit fixes `DefaultErrorWebExceptionHandler` to use `HttpStatus.value()` when attempting to resolve error views. Closes gh-15083
