Describe the feature

Update Lambda examples to use NODEJS_18_X

Use Case

There are multiple examples on Lambda Node.js 10.x and 12.x which are no longer supported by Lambda:

• 10.x https://github.com/search?q=repo%3Aaws-samples%2Faws-cdk-examples%20NODEJS_10_X&type=code
• 12.x https://github.com/search?q=repo%3Aaws-samples%2Faws-cdk-examples%20NODEJS_12_X&type=code

And per official documentation, Node.js 14.x and 16.x will be following deprecation phase 1 on Nov 27, 2023 and Jun 12, 2024 respectively. These are also used in CDK examples:

• 14.x https://github.com/search?q=repo%3Aaws-samples%2Faws-cdk-examples%20NODEJS_14_X&type=code
• 16.x https://github.com/search?q=repo%3Aaws-samples%2Faws-cdk-examples%20NODEJS_16_X&type=code

Proposed Solution

Upgrade all examples to use NODEJS_18_X
