Singularity has been renamed to Apptainer

[sverhoeven]

See https://apptainer.org/news/community-announcement-20211130

The action should have support for Apptainer once a release for it has been made.

We should make a fork of this action to new action called setup-apptainer to make clear the action is for apptainer and not for the singularity products offered by the syslabs company.

The https://github.com/hpcng/singularity repo has been moved to https://github.com/apptainer/singularity, it has the old singularity versions and should be used to download+build from. The repo URL should be changed in this repo and in https://github.com/eWaterCycle/singularity-versions

+1 - I just tried a version of Singularity (from sylabs/singularity) and it didn't work, and this was because it was trying to install from hpcng, which now redirects to apptainer.

I agree with @sverhoeven - the name "singularity" is staying with Sylabs so should be represented here in setup-singularity, and setup-apptainer could be a different repo.

Is the eWaterCycle team still maintaining this or should I provide a version on the singularityhub org?

I have created https://github.com/eWaterCycle/setup-apptainer .
The setup-apptainer is much simpler as Apptainer releases binary deb files so the GitHub action just downloads and installs those.
