Quarkus REST Client extension is not enabling SSL native by default as documented
**Describe the bug**
In the guide https://quarkus.io/guides/native-and-ssl there is a mention that quarkus-rest-client extension should automatically enable SSL in native but SSL doesn't work without explicit property `quarkus.ssl.native=true`/

**Expected behavior**
SSL works by default as documented.

**Actual behavior**
SSL doesn't work without explicit property.


**To Reproduce**

https://github.com/xstefank/quarkus-rest-client-extension

**Configuration**
```properties
# Configuration file
# key = value

# uncomment to make SSL work in native
#quarkus.ssl.native=true
```

**Additional context**
Maybe this can be related to the plain use of the RESTEasy JAX-RS client? However, I still think this should work.
