[Bug]: run-singularity workflow doesn't run command inside container

[SarahNadeau]

What container were you trying to use, and how were you attempting to use it?

The run-singularity.yml workflow pulls a docker image and runs it as a Singularity container. It's supposed to run a command inside the container (pwd by default), see this line.

Instead, it looks like the command gets run on the GitHub actions runner, not in the container (e.g. here).
