[Feature Request] Add support for deployment via Cloud9 instances

[nelomsmn]

Opening this issue as a feature request to add support for deploying this solution via AWS Cloud9.

Currently, when using Cloud9 to deploy the "Embeddings-Foundational-LLM-ChatBot" solution, we run into an error on the "lambda_langchain_layer" unzipped size being larger than lambda's 250Mb size constraint. As noted in the ReadMe for "Embeddings-Foundational-LLM-ChatBot", this solution may not function correctly when deployed via Cloud9 or similar cloud-based development environments.
