Support alternating row background

Much like Apple's Table component supports them.

In Monterey and onward, Lists support this style with the following modifier:

TablerList(listConfig,
                           header: header,
                           row: row,
                           results: fruits)
    .listStyle(.inset(alternatesRowBackgrounds: true))

It'd be nice to support a similar effect for Stack and Grid based tables.
