AWS documentdb documentation change

File: documentdb/latest/developerguide/toLong.md

Summary

Added new documentation page for the $toLong operator in Amazon DocumentDB, including description, parameters, MongoDB shell example, and code examples in Node.js and Python

Security assessment

This change adds documentation for a new data type conversion operator ($toLong) in DocumentDB version 4.0. The documentation includes standard code examples with TLS connection parameters (tls=true&tlsCAFile=global-bundle.pem) which is a security best practice, but this is not new security documentation - it's standard secure connection practice. There is no evidence this addresses a specific security vulnerability or incident.

+# $toLong
+
+New from version 4.0
+
+The `$toLong` operator in Amazon DocumentDB is used to convert a value to a 64-bit integer (long) data type. This can be useful when you need to perform arithmetic operations or comparisons on numeric values that may be stored as strings or other data types.
+
+**Parameters**
+
+  * `expression`: The expression to convert to a 64-bit integer.
+
+
+
+
+## Example (MongoDB Shell)
+
+This example demonstrates how to use the `$toLong` operator to convert a string value to a 64-bit integer.
+
+**Create sample documents**
+    
+    
+    db.numbers.insertMany([
+      { _id: 1, value: "42" },
+      { _id: 3, value: "9223372036854775807" }
+    ]);
+
+**Query example**
+    
+    
+    db.numbers.aggregate([
+      {
+        $project: {
+          _id: 1,
+          longValue: { $toLong: "$value" }
+        }
+      }
+    ])
+
+**Output**
+    
+    
+    [
+      { "_id" : 1, "longValue" : 42 },
+      { "_id" : 3, "longValue" : 9223372036854775807 }
+    ]
+
+## Code examples
