Uses pre-built containers for faster builds

This update switches the Quarto build workflow to utilize pre-built containers.

These containers include fixed versions of Quarto, R, Python, and TeX Live, ensuring consistent and faster builds across different environments.

The workflow now leverages these pre-built images for both Linux and Windows, streamlining the build process and improving reliability.
The workflow now outputs versions and system resources.
