Support "Allow" header for 405 errors

[jakejohns]

The HTTP 405 Method Not Allowed client error response status code indicates that the server knows the request method, but the target resource doesn't support this method. The server must generate an Allow header in a 405 response with a list of methods that the target resource currently supports.

Thanks!

I think instead of a new allow method, it's better to have a more generic headers method.

protected function allow(ResponseInterface $response, Throwable $error): ResponseInterface

The method can check if the getHeaders method exists in the $error instance and apply these headers to the response.
