Describe the doc issue

Several tutorials in the OpenCV-Python documentation (located at https://docs.opencv.org/4.x/d6/d00/tutorial_py_root.html) have either the "Additional Resources" or "Exercises" sections (or both) empty. This can lead to incomplete information and potential confusion for readers seeking further guidance or practice opportunities.
Example from tutorial_py_image_arithmetics.html:

Example from tutorial_py_features_meaning.html

Fix suggestion

Remove the empty "Additional Resources" and "Exercises" fields from the affected tutorials to maintain consistency and clarity in the documentation.
