AWS documentdb documentation change

Summary

Added documentation for the $abs aggregation operator in Amazon DocumentDB with examples in MongoDB Shell, Node.js, and Python

Security assessment

This change adds standard documentation for a mathematical operator ($abs) in Amazon DocumentDB. The examples show typical usage patterns for aggregation pipelines and include standard connection strings with TLS parameters. There is no evidence of addressing a security vulnerability, weakness, or incident. The connection strings shown include standard security parameters (tls=true, tlsCAFile) that are already documented elsewhere.

+
+# $abs
+
+The `$abs` operator in Amazon DocumentDB returns the absolute value of a number. It can be used in the aggregation pipeline to perform mathematical operations on numeric fields.
+
+**Parameters**
+
+  * `number`: The numeric expression for which the absolute value will be returned.
+
+
+
+
+## Example (MongoDB Shell)
+
+This example demonstrates the usage of the `$abs` operator to find the absolute value of a numeric field.
+
+**Create sample documents**
+    
+    
+    db.numbers.insertMany([
+      { "_id": 1, "value": -5 },
+      { "_id": 2, "value": 10 },
+      { "_id": 3, "value": -3.14 },
+      { "_id": 4, "value": 0 }
+    ]);
+
+**Query example**
+    
+    
+    db.numbers.aggregate([
+      { $project: {
+        "_id": 1,
+        "absolute_value": { $abs: "$value" }
+      }}
+    ]);
+
+**Output**
+    
+    
+    [
+      { "_id": 1, "absolute_value": 5 },
+      { "_id": 2, "absolute_value": 10 },
+      { "_id": 3, "absolute_value": 3.14 },
+      { "_id": 4, "absolute_value": 0 }
+    ]
