Removed the upper pins for Flask and Werkzeug.

[moorepants]

Upper pins make it very difficult or even impossible to manage conda environments and Dash has unwisely added them upstream. In this case, we should ensure the conda packages work smoothly within the conda ecosystem and not adopt these upper pins in the feedstock.

As mentioned here https://github.com/conda-forge/dash-feedstock/pull/129#issuecomment-1576382853

"I would rather we see how it goes without the upper pins. If we starting getting bug reports on it, then we can assess." -- moorepants

We have not received any bug reports, so I am removing the upper pins that were added without review in:
