Add a new serverless pattern that deploys a .NET 10 Lambda function with an Amazon S3 Files file system mounted at /mnt/s3data. The function performs standard file operations (read, write, list) using the local filesystem without S3 API calls.

Uses isolated VPC subnets with an S3 Gateway VPC endpoint.

Add a new serverless pattern that deploys a .NET 10 Lambda function with
an Amazon S3 Files file system mounted at /mnt/s3data. The function
performs standard file operations (read, write, list) using the local
filesystem without S3 API calls.

Uses isolated VPC subnets with an S3 Gateway VPC endpoint instead of a
NAT gateway for a more cost-effective design.
