Typo found in tutorial

[Javier Sanchez]

@saurabhwjha found a typo in https://github.com/LSSTDESC/DC2-analysis/blob/master/contributed/cosmoDC2_TheMovie.ipynb

In particular in the line plt.bar(hp['loc'].bvalues, hp['count'].values, step, color='w', edgecolor='k') it should be: plt.bar(hp['loc'].values, hp['count'].values, step, color='w', edgecolor='k')

I'll go ahead and quickly edit it

Thanks @saurabhwjha for spotting it, and @fjaviersanchez for taking care of it!
