refactor: remove ppc64le and s390x architectures

Remove less commonly used architectures from build platforms to streamline the
build process and reduce build times. This change only removes architectures
without modifying the existing workflow structure.

- Remove linux/ppc64le platform
- Remove linux/s390x platform
