Refactor test scripts and README for MSSQL backup functionality

- Updated README.md to reflect new script paths for MSSQL tests.
- Added new test scripts for Kubernetes and Docker Compose environments, including setup for MinIO.
- Introduced k8s-statefulset-test.yaml for deploying MSSQL with a backup sidecar.
- Created setup-minio-k8s.sh for automated MinIO deployment in Kubernetes.
- Enhanced test-mssql-k8s-with-minio.sh to streamline the testing process with MinIO.
- Added comprehensive test-mssql-k8s.sh for validating MSSQL backup and restore operations.
- Included test-mssql.sh for Docker Compose testing of MSSQL backup functionality.
