bug#45835: (gnu machine digital-ocean) installs old Guix

[Ricardo Wurmus]

The (oddly named) procedure “guix-infect” in (gnu machine digital-ocean)
contains a Bash script that installs Guix 1.0.1 and sets the
GUILE_LOAD_PATH to that of Guile 2.2.

Likewise, “add-static-networking” in the same module sets
GUILE_LOAD_PATH to 2.2.

It seems to me that this should be updated to install the latest version
of Guix and set the load path to that of Guile 3.0.

I also wonder if there might not be a better way to deploy Guix quickly,
for example by using a relocatable pack of Guix and using “guix copy”
instead of executing a shell script.
