When attempting to plot three aligned subplots in Plots.jl’s pythonplot() backend, the following error message is displayed:

`ERROR: Python: AttributeError: 'GrouperView' object has no attribute 'join' Python stacktrace: none`

The same error was reported in SO and a [recommendation](https://stackoverflow.com/a/77419183) was given to downgrade matplotlib to 3.7 or 3.6.

How to perform such a downgrade?
