Add Lambda function and configure deployment

This commit adds a new Lambda function with its associated Dockerfile, package.json and deployment configuration files. It also includes the necessary updates to the GitHub Actions workflow and the Terraform configuration for automatic deployment of the function. Additionally, the .gitignore file has been updated to ignore the newly added directories and files related to the Lambda function installation and execution.
