fix(fault injection): add find package to cmake

[tkimura4]

Description

I fixed build error of fault injection.

--- stderr: fault_injection
CMake Error at /opt/ros/humble/share/ament_cmake_auto/cmake/ament_auto_add_library.cmake:66 (add_library):
  Target "fault_injection_node_component" links to target
  "pluginlib::pluginlib" but the target was not found.  Perhaps a
  find_package() call is missing for an IMPORTED target, or an ALIAS target
  is missing?
Call Stack (most recent call first):
  CMakeLists.txt:7 (ament_auto_add_library)

Failed   <<< fault_injection [1min 12s, exited with code 1]

(I don't understand why fault_injection depends on pluginlib package.
There are many other packages to register plugins by rclcpp_components_register_node, but any other module without fault_injection do not cause error. )

Is it better to add pluginlib dependency into package.xml?
