Healthcare tags do not render on closed ways without area=yes

[jeisenbe]

Expected behavior

The key "healthcare=" should be imported as a polygon so that the icons for clinics, hospitals etc will render properly.

Actual behavior

A closed way ("area") tagged with healthcare=* alone does not import or render
Adding "area=yes" causes it to render

Solution

Add 'healthcare' to list of local polygon_keys in openstreetmap-carto.lua

Adding 'healthcare' to list of local polygon_keys in openstreetmap-carto.lua will work as soon as the database is re-imported. I believe it will also work with any features that have been added or edited, since these are separately imported into the rendering database.
