nixos/caddy: update ca option

The generated json configuration returns this warning:
the 'issuer' field is deprecated and will be removed in the future; use 'issuers' instead

Updated the config to use "issuers" instead of "issuer"

Also, now it's possible to set the ca option null to not inject
automatically any ca. This is useful if you don't want to generate any
certificates or if you want to define a more fine-graned ca config
manually (e.g.: use different ca per domain)
