AWS documentdb documentation change

File: documentdb/latest/developerguide/year.md

Summary

Added documentation for the $year operator in Amazon DocumentDB, including description, MongoDB Shell example, and code examples in Node.js and Python

Security assessment

This change adds documentation for a date/time operator ($year) with standard usage examples. The code examples include TLS connection parameters (tls=true, tlsCAFile=global-bundle.pem) which are standard security practices for DocumentDB connections, but this is not new security documentation - it's just showing standard connection strings. No evidence of addressing a specific security vulnerability or incident.

+Example (MongoDB Shell)Code examples
+
+# $year
+
+The `$year` operator in Amazon DocumentDB extracts the year component from a date or timestamp.
+
+**Parameters**
+
+  * `expression`: The date or timestamp expression from which to extract the year component.
+
+
+
+
+## Example (MongoDB Shell)
+
+The following example demonstrates how to use the `$year` operator to extract the year component from a date field.
+
+**Create sample documents**
+    
+    
+    db.events.insertMany([
+      { "_id": 1, "date": ISODate("2023-04-15T00:00:00Z") },
+      { "_id": 3, "date": ISODate("2021-12-31T00:00:00Z") }
+    ]);
+
+**Query example**
+    
+    
+    db.events.aggregate([
+      { $project: { year: { $year: "$date" } } }
+    ]);
+
+**Output**
+    
+    
+    [
+      { "_id": 1, "year": 2023 },
+      { "_id": 3, "year": 2021 }
+    ]
