[Repo Request]: singularity build error in github actions

[erinyoung]

What functionality is this repo missing?

There is an error when deploying images :

run-singularity / build_singularityThe following actions uses node12 which is deprecated and will be forced to run on node16: eWaterCycle/setup-singularity@v7. For more info: https://github.blog/changelog/2023-06-13-github-actions-all-actions-will-run-on-node16-instead-of-node12-by-default/

This happens when building an image with singularity, and does not impact docker image creation. Should be an easy fix, though.
