Tagging the 2.3.1 release

2.3 Release

Tagged v2.2.1

Release of version 2.2

Fix apptainer#180 (Potential kernel panic when running a container wi…

…th corrupted ext filesystem)

Moved /environment generation to early in bootstrap

Remove doc reference to "import -t" (for now)

It is currently broke due to 'set -u' and on testing, I can't seem
to get it working properly based on the docs/help:

$ sudo singularity import -t docker ubuntu /tmp/Moo.img
ERROR: No Docker image specified (with --file)

So to work around the problem and not delay the release, I am hiding
the feature so we can still debug and fix, but not delay release on
a broken feature.
