Missing support for UnprocessableContent in WebClientResponseException.create(HttpStatusCode, ..) methods

[hanson76]

Sprig Framework 7.0 deprecates HttpStatus.UNPROCESSABLE_ENTITY in favor of HttpStatus.UNPROCESSABLE_CONTENT but the static WebClientResponseException.create(HttpStatusCode statusCode, ...) method is missing it in it's switch statement.

That affects the usage of onErrorResume() on on responses, trying to use onErrorResume(WebClientResponseException.UnprocessableContent, () -> {}) will not be executed
