micronaut-http-client not configuration properties not working

### Issue description

I am new to the concept of micronaut-http-client and it's inner working. I have been following https://guides.grails.org/grails-micronaut-http/guide/index.html and https://docs.micronaut.io/latest/guide/#clientConfiguration. With these I am able to make a blocking http request to my service. However, I have tirelessly tried and failed to inject configuration via application.yml

```
micronaut:
codec:
json:
additionalTypes:
- text/javascript
http:
client:
read-idle-timeout: 1m
max-content-length: 10m
read-timeout: 30s
```

```

code to make http blocking call

```
def makeBlockingCall(requestFormat) {
String baseUrl = Holders.config.grails.url
HttpClient client = HttpClient.create(baseUrl.toURL())
HttpRequest request = HttpRequest.POST(UriBuilder.of('/')
.build(), requestFormat)
.contentType(MediaType.APPLICATION_JSON)
.header("client-id","xxx")
.header("client-name","xxx")
.header("ticket","xxx")

def response = Mono.from(client.exchange(request, String))
.block()
.body()
ObjectMapper objectMapper = new ObjectMapper()
objectMapper.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, true)
return objectMapper.readValue(response, ResponseFormat)
}
```

When I make an http request as per the configuration the request doesn't wait until 30s before timing out but resorts to default always.
