Include mount commands in user_data_script for Terraform instance initialization

This commit updates the user_data_script in the Terraform script to include mount commands for better initialization of the instance. The added mount commands ensure proper mounting of specified devices to relevant directories during the first boot of the instance. This adjustment addresses the requirement for mounting operations in the infrastructure setup.
