Verify that the commits referenced actually exist.
Potential fixes:
Either determine the correct git command to allow checking out of a git hash.
Pass in the branch references to the workflow rather than the commit reference (this might not work because we need the last common ancestor of the source and target PR branches)
Background
See https://github.com/ACCESS-NRI/access-om3-configs/actions/runs/11431185640/job/31799822071#step:4:82, workflow inputs found here https://github.com/ACCESS-NRI/access-om3-configs/actions/runs/11431185640/job/31799822071#step:1:27
Specifically, using a commit hash rather than a branch means that the initial clone of the configuration repository fails to checkout the given commit. The failed step is here: https://github.com/ACCESS-NRI/access-om3-configs/actions/runs/11431185640/job/31799822071#step:4:10.
