Make XChange compatible with jakarta.ws.rs-api 3.x

[ppalaga]

As far as I can see, the jakarta.ws.rs-api is pulled transitively via com.github.mmazi:rescu. Once a com.github.mmazi:rescu release compatible with jakarta.ws.rs-api 3.x is available, XChange should be adjusted as well. This is currently blocked by https://github.com/mmazi/rescu/issues/142

It would be nice to have this to be able to use XChange on Quarkus 3.x.
