The singularity package was renamed to apptainer

In fedora, singularity-3.8.7 was replaced with apptainer-1.1.0

The package was split into apptainer and apptainer-suid (root).

Use fedora instead of rocky, since it is smaller (and shorter).

SingularityCE has not been packaged as dnf, only from sylabs.io
