Add .env file to .gitignore in tools/deployment/presto-clp #1422
Description
The generated .env file in tools/deployment/presto-clp/ should be added to a .gitignore file to prevent it from being committed to the repository.
Context:
The set-up-config.sh script generates a .env file containing environment variables at tools/deployment/presto-clp/.env. This file may contain sensitive information (database credentials, etc.) and should not be tracked by Git.
