Subject: [bug#62153] Cover lever typo in guix pack format example

From: Oleg Pykhalov <[email-masked]>

The cover lever guix pack example should be:

    ./pre-inst-env guix pack -f docker-layered --entry-point=bin/bash -S /bin=bin bash hello

instead of

    ./pre-inst-env guix pack -f docker --entry-point=bin/bash -S /bin=bin bash hello

Apologies,
Oleg.
