object async_generator can't be used in 'await' expression

[longxiang1025]

I'm trying to re-run the sample script to download ARD data (https://github.com/planetlabs/notebooks/blob/master/jupyter-notebooks/analysis-ready-data/ard_1_intro_and_best_practices.ipynb). In Line 9, when I tried to conduct the actual search, this error popped up.

This error is also identified in https://github.com/planetlabs/planet-client-python/issues/845. The notebook should be updated (tag: @mkshah605 ). In the mean time, just drop the await command.
