Fix Permissions Analysis Tool app

[chunheisiu]

Description

Fix the following issues with the Permissions Analysis Tool app:

1. Added a resource type mapping to map Warehouse to SQLWarehouse to match with API response.
   The brickhound_vertices table has no node_type = 'Warehouse', only SQLWarehouse. Thus, adding this mapping so that relevant SQL warehouses records are correctly returned.
2. Added missing resource types emojis.
