Description
Please also take a look at #17568 (comment) for updated context on this issue.
The documentation repository is becoming quite large (#17564 (comment)) and in particular there are 66MB of images. It might be worth checking if the size of lagest ones couldn't be reduced a bit by adjusting matplotlib options in examples. In the _images/ folder,
