Fix non-root experience with snap package

See snapcraft forum post here for a more in-depth explanation of the current issue that I am facing with the Apptainer snap package: https://forum.snapcraft.io/t/strange-discrepancy-between-root-and-non-root-user-when-using-snap-package/32906.

TL;DR - the snap package works in classic confinement if using sudo, but breaks if trying to use as regular user. This is not supposed to happen with Apptainer since it is geared towards users who do not have root privileges on the host system.

Write documentation for Apptainer snap

Enable multiarch support for snap package

Need to add support for architectures arm64, armhf, ppc64el, and s390x. arm64 is the most important architecture to enable since it is the up and coming platform for HPC.
