Test, DO NOT MERGE

This is a self-test of GitHub actions.

@weihuang-jedi @RussTreadon-NOAA It appears that there may be an issue with JCSDA's version of spack. Without making any substantial changes, the build step is failing to locate a root directory. I suggest working with someone from the spack-stack team to determine the root cause.

Thank you @DavidHuber-NOAA for looking into this and sharing your insights - much appreciated!

@weihuang-jedi : this test PR and your PR #88 report the same failure

Cloning into 'spack'...
==> Error: [Errno 2] No such file or directory: '/home/runner/work/GSI-utils/GSI-utils/spack/etc/spack/defaults/${SPACK_STACK_DIR}/spack-ext/lib/jcsda-emc/spack-stack/stack/cmd'
Error: Process completed with exit code 3.

I would expect ${SPACK_STACK_DIR} to be replaced with a value and not remain in the listed path. Perhaps variable SPACK_STACK_DIR is not defined or is not properly expanded. Can you work with the spack-stack team to sort this out?

Sorry I dropped the ball here.
This looks like a CI testing issue. Since I did not run those CI testing, and not familiar with the procedure there, I do not know where to start of resolving this.
I do not think this is a spack-stack issue.
