Updated CUDA and MPI Versions in Makefile for LLNL CUDA CORAL EA Example

[kulnaman]

The old version of MPI casued compilation issues on LLNL's CORAL EA systems. To address this, I've upgraded both the CUDA and MPI versions to a much newer releases. After making these changes, I tested the code on the Lassen cluster to confirm its functionality and compatibility. These updates should ensure better performance and robustness on CORAL EA systems.
