feat: add Node.js 18 Lambda runtime (#2289)

Updates to LambdaRuntime to deprecate NODEJS_10_X and inclusion of NODEJS_18_X

https://docs.aws.amazon.com/lambda/latest/dg/lambda-runtimes.html

All tests pass and tested with project using NODEJS_18_X.

Inclusion of Go in CONTRIBUTING guidelines as build failed before installing Go.
