[bug#71586] [PATCH] services: web: Improve nginx formatting for extra-content

[Richard Sent <richard@freakingpenguin.com>]

* gnu/services/web (default-nginx-config): When extra-content is a list, add 4
space indentation and a newline to every line. If it's a string, continue
inserting it directly. This makes the list serialization behavior more
consistent with other services.
