Fix UnprocessableContent support in WebClientResponseException

Prior to this commit, `WebClientResponseException` would only support
the deprecated "unprocessable entity" status.
This commit adds the missing support for "unprocessable content" when
creating exceptions with `WebClientResponseException#create`.

Fixes gh-35802
