Incorrect extraction of relative height metrics in `GEDI_L2A_V2_Tutorial.ipynb`

[maawoo]

In section "4.2 Plot Relative Height Metrics" of the notebook some relative height metrics are extracted like this:

rh25 = rhShot[24]                           # 25% 
rh50 = rhShot[49]                           # 50%  
rh75 = rhShot[74]                           # 75% 

To my understanding this should be wrong, as the index of each array starts at 0 and "each shot contains 101 values representing rh at 0-100%". Later on in the notebook the metrics are extracted in the correct way.
