Pull out long inline scripts from run: steps, add testing

[CodeGat]

similar to https://github.com/ACCESS-NRI/build-cd/blob/main/scripts/generate-build-metadata.bash which has had a large script pulled out and tested, we need to do this for more scripts. This will make it easier to test independently. This should be the case for all long-running scripts.

Some candidates:

• build-cd/.github/workflows/ci.yml

  	# for each of the modules
  	for DEP in $DEPS; do
  	DEP_VER=''
  	if [[ "$DEP" == "${{ needs.defaults.outputs.root-sbd }}" ]]; then
  	DEP_VER=$(yq '.spack.specs[0] | split("@git.") | .[1]' spack.yaml)
