Optimize CI pipeline by bundling setup steps

Streamlined the setup process in the GitHub Actions workflow by
combining system updates and package installations into a single step.
Removed the action for setting up CMake, instead directly installing it
along with build requirements, reducing redundancy and improving build
times. These adjustments enhance the efficiency of the continuous
integration process.
