uberjar : merged ressource not foundable

[dufoli]

Describe the bug

On quarkus CXF extension, we have an issue because CXF is compound of few library and they contain resource with the same name. So we need to merge them.

solution was to use the quarkus in build time to merge resource and produce a unique one.
We have done so in PR by generating GeneratedResourceBuildItem:
quarkiverse/quarkus-cxf#218

and quarkus code PR add generated ressource to uberjar in priority to regular one:
#17199

Thanks to that, now it build with uberjar but on runtime, resource are not found.
cf comment:
quarkiverse/quarkus-cxf#238 (comment)

remark: this problem happend too in native mode because it use uberjar.
