Lambda deprecating Node.js 14.x runtime

[wilsenhc]

According to the AWS Lambda Supported Runtimes, Node.js 14.x runtime will be deprecated starting Nov 27, 2023, in Phase 1 deprecation which means the following:

Phase 1 - Lambda no longer applies security patches or other updates to the runtime. You can no longer create functions that use the runtime, but you can continue to update existing functions. This includes updating the runtime, and rolling back to the previous runtime. Note that functions that use a deprecated runtime are no longer eligible for technical support.

This means new functions can not be created using Node.js 14.x which is the default runtime in the base LambdaFunction of this package.
