bug#56678: certbot mcron job fails

[Ludovic Courtès]

Hello,

‘certbot-service-type’ defines an mcron job that invokes ‘certbot’ with
a fairly long list of arguments.  However, that command line appears
to be incorrect, or at least it is on bayfront.guix where I tested it:

What should we do about “Please choose an account”?
