Description of the PR

This pull request updates the Dockerfiles used for the swagger-generator module to streamline the build process and keep the base images up to date. The main changes include upgrading the Red Hat UBI base image version, consolidating package installation commands, and simplifying multi-step RUN commands for efficiency and maintainability.

Base image and package installation updates:

• Upgraded the base image from redhat/ubi9-minimal:9.6 to redhat/ubi9-minimal:9.7 in both Dockerfile and Dockerfile_root to ensure the latest security patches and features are used. [1] [2]
• Consolidated multiple microdnf install commands into a single command in Dockerfile for improved build efficiency.

Build process simplification:

• Combined several sequential RUN commands (such as directory creation, permission changes, and file removal) into single RUN statements in both Dockerfiles, making the Dockerfiles cleaner and reducing the number of layers in the resulting images. [1] [2]
• Streamlined user and group creation as well as ownership changes into a single RUN command in Dockerfile for better readability and efficiency.
