add the given list of societies to database

[dvishal485]

• list of society shared on whatsapp
• create a getter controller and route
• no requirement of setter controller right now because create/update will rarely be required after initialization and minor changes can be done using mongodb compass directly as of now
• make the interface have fields name, full_name and a description

interface Society {
    name : string
    full_name? : string
    description? : string
 }

• keep description undefined for all soc right now, can be populated later on
• no need to protect route (should be public api route)
• to add in db, you can simply use ur own mongo instance and then share the same as JSON by exporting from mongodb compass
