Add Iceberg SQL Examples with Glue and S3 Tables Catalogs

Purpose of the change

Add two new examples demonstrating how to write streaming data to Iceberg tables using SQL operations with different catalog implementations:

1. Using AWS Glue Data Catalog
2. Using Amazon S3 Tables

Both examples showcase implementation of streaming stock price data to Iceberg tables using Flink SQL, providing users with patterns for both Glue and S3 Tables integration.

Verifying this change

Local Testing

Tested both examples locally in IntelliJ:

1. Configure flink-application-properties-dev.json with appropriate S3 bucket/ARN
2. Run the main application class
3. Verified data generation and table creation in both Glue Data Catalog and S3 Tables
4. Confirmed data writing through SQL queries

Example output from Glue example:

mysql> SELECT * FROM iceberg.stock_data LIMIT 5;
