Update requirements.txt

Downgrade Werkzeug because we are using `from werkzeug.contrib.atom import AtomFeed` in the **NeighborlyFrontEnd/app.py** file. As per changelogs available [here](https://werkzeug.palletsprojects.com/en/1.0.x/changes/), the atom is deprecated, and and is better served by a dedicated library `feedwerk` where needed.
