CI 2.0 adding Rust examples #2

	# This workflow is a demo of how to run all examples in the Icicle repository.
	# For each language directory (c++, Rust, etc.) the workflow
	# (1) loops over all examples (msm, ntt, etc.) and
	# (2) runs ./run.sh in each directory.
	# Each script should return 0 for success and 1 otherwise.
