### Proposal It appears that GlobalSettings.update_global_settings() expects to receive back the updated setting when posting to `__admin/settings` but according to [the documentation](https://wiremock.org/docs/standalone/admin-api-reference/#tag/System/paths/~1__admin~1settings/post) the actual successful response is blank. Thus when I attempt this, the setting is successfully applied but raises a `JSONDecodeError` from requests. ### Reproduction steps Based on the unit test I see [here](https://github.com/wiremock/python-wiremock/blob/master/tests/test_resources/test_settings/test_settings_resource.py), I attempted to set a global fixed delay as follows: `GlobalSettings.update_global_settings(GlobalSetting(fixed_delay=350))` with wiremock:2.32.0. ### References _No response_
