[bug#47719] [PATCH] guix: scripts: system: Realign action docstrings

[Andrew Tropin <andrew@trop.in>]

Long actions like switch-generations and delete-generations make actions help
table from `guix system --help` to be missaligned.  This commit alignes all
the action docstrings to the longest action name (delete-generations).
