Subject: [PATCH] Refactor AMI configuration in morpheus.tf and add
 base_images.tf and variables.tf

This commit refactors the AMI configuration in morpheus.tf by introducing a local variable for the AMI ID and updating the module configuration accordingly. Additionally, it adds the base_images.tf file, which contains a data source for the AWS SSM parameter "rhel9_ami". Finally, it includes the variables.tf file, which defines the "use_rhel9_ami" variable to control whether to use the RHEL 9 AMI.
