Update dockerfiles and docker-build.yml (#2389)

* chore: Update docker-build.yml to disable pre-release by default

* chore: Update Dockerfiles to set LANGFLOW_HOST and LANGFLOW_PORT

The Dockerfiles have been updated to set the environment variables LANGFLOW_HOST and LANGFLOW_PORT. This ensures that the correct host and port are used when running the langflow application.

* 🔧 (build_and_push_backend.Dockerfile): remove unnecessary host and port configuration to simplify the Dockerfile and focus on backend-only functionality

* chore: Update LANGFLOW_CONFIG_DIR in docker-compose.yml

The LANGFLOW_CONFIG_DIR environment variable in docker-compose.yml has been updated to /app/langflow. This change ensures that the correct directory is used for storing logs, file storage, monitor data, and secret keys.
