Creating Series & DataFrames/Pokemon

[max-alletsee]

Thanks again for creating this amazing collection of exercises.
Two quick things:

1. I made sure that the Solutions file shows the actual solutions. (Before, it showed just empty cells, like a copy of the Exercises file.)
2. The name of the target dataset was missing in the instruction.

Sorry for taking so long and thank you again for providing a PR.

If you feel like creating new exercises, please, feel free! :)

Thanks for merging into the master.
I would be happy to contribute an exercise (e.g. related to indexing), but I would need to find the time to develop this properly. So probably not a short-term goal, but not a mid-term goal.
