Problem

The only style sheet examples that show the default grid color in that style are the styles that turn grids on by default. I think it'd be useful to show which color the grid defaults to when turned on, in part to flag color choices such as#23598

Suggested improvement

I suggest turning on the grid for the line example since my guess is that's the most common use case for grids. This is a good-ish first issue since it involves adding something like anax.grid call to one of the plots in the example (https://github.com/matplotlib/matplotlib/blob/main/examples/style_sheets/style_sheets_reference.py) but there might be lots of back and forth on the PR on which example gets the grid.
