camel-quarkus-pdf: register PDFBox's resource directory instead of a hand-listed constant

`camel-quarkus-pdf` registers PDFBox's native resources from a hand-listed constant, `PdfProcessor.RUNTIME_RESOURCES`. It has drifted: it names `icc/ISOcoated_v2_300_bas.icc`, which PDFBox 3.0.8 replaced with `icc/CGATS001Compat-v2-micro.icc` — so it registers a resource not in the jar and misses the real ICC profile (latent native failure for PDFs that load the default output-intent profile).

Fix: replace the list with `NativeImageResourceDirectoryBuildItem("org/apache/pdfbox/resources")`, so native image embeds whatever the jar ships and the set self-heals on upgrades. See #9078 for the same change in `langchain4j-ingest` as an example.
