[docs] Add examples of poi layer kind_detail values

[nvkelso]

@sensescape has been auditing icon name values against tilezen kind and kind_detail values and discovered we don't fully document the kind_detail values for the pois layer.

Right now in the code we pass thru any and all values of cuisine and sport – whatever is in OpenStreetMap gets passed thru – which is one of the last things to not have a white list.

Looks like religion should be kind_detail, but isn't yet. Tracking that in #1134.
