We'll need to update this in the example as well. I can do that :)

What do we need to update?

From PR description:

I included a small tweak to the tsx snippet as well in order to:

• render the Pokemons list in a more pleasant way (see below)
• avoid using index for key, since it's not considered a good practice and the Pokemons names are a better candidate

Since the tutorial hosted in this repo is different from the one in the linked documentation change only the key prop should be changed
