[css-grid-1][css-grid-2] Set min-height for ex 39 (w3c#6214)

SiarheiBobryk · web-flow · commit 30bb9fab151f · 2021-04-16T10:45:37.000-07:00
Set the `min-height` property for the `.grid` class to make the
`align-content: center;` work much more clear. `align-content: center;`
has no sense if we run the example 39 as it is.
