text: Title: test_pipleline in RTMDet config file
  Body: Hello
  How are you?
  I am using the latest released version (3.2.0) of mmdetection.
  I found that there is an issue in test_pipeline of RTMDet config file.

  I think that "LoadAnnotations" should be placed right after "LoadImageFromFile".
