DOC: Fix typo in min_rows / max_rows option example
 - Fix typo in example
 - Regenerated output also seems to fix a bad output in the next line (out 32 in current online documentation) where df is truncated, when it shouldn't by according to the code 

Also, when looking at the [current online documentation](https://pandas.pydata.org/pandas-docs/stable/user_guide/options.html), more things seem to be off. The example about `display.expand_frame_repr`does not show any difference between the two settings. Rebuilding the page seems to fix this, my local version looks good.  @datapythonista this looks fine to me, but I don't know this area that well.
 Great thanks @tobycheese
