[8pt] GitHub Linting warning

[RobHanna-NOAA]

Note: Now part of 1377 EPIC: FIM Sys Admin Tasks (and a few related FIM tasks)

This one has been around for quite a while (maybe in the spring?). It is not a problem yet, but I would hate for it to catch us off guard.

When the linting tool is run as part of a git checking, in the linting logs, it shows:

		- The following actions use a deprecated Node.js version and will be forced to run on node20: actions/checkout@v3, actions/setup-python@v4, actions/cache@v3. For more info: https://github.blog/changelog/2024-03-07-github-actions-all-actions-will-run-on-node20-instead-of-node16-by-default/
