update instruction on main.tex

[karidx]

In step 3, when I ran jupyter notebook, I got the error saying that jpyter-notebook was not found.

(XCS330) xxx@xxx-MacBook-Air XCS330-PS1 % jupyter notebook
...
Jupyter command `jupyter-notebook` not found.

I then ran conda list to view all the dependencies in the environment. Turns out that notebook is not in the dependency list.

conda list

...
ncurses                   6.4                  h313beb8_0  
nest-asyncio              1.6.0           py310hca03da5_0    anaconda
networkx                  3.4.2                    pypi_0    pypi
nltk                      3.9.1                    pypi_0    pypi
numexpr                   2.10.1          py310h5d9532f_0  
numpy                     2.2.2           py310h3b2db8e_0  
numpy-base                2.2.2           py310ha9811e2_0  
...

Therefore we should update the instruction to install notebook.
