Or fix the CI?

I aslo build QGIS in ArchLinux, fix build only use find_package Config Mode.

the new way use Protobuf is just add .proto file as last parameter to add_library() function.

add_library(qgis_core ${LIBRARY_TYPE} ${QGIS_CORE_SRCS} ${QGIS_CORE_HDRS} ${QGIS_CORE_PRIVATE_HDRS} ${IMAGE_RCCS} vectortile/vector_tile.proto )
target_link_libraries(qgis_core protobuf::libprotobuf-lite)
protobuf_generate(TARGET qgis_core)

Unless Ubuntu update the version of Protobuf package , CI will always fail.
