bug#46961: [PATCH v3 3/4] services: certbot: Reload nginx in deploy hook.

[Carlo Zancanaro <carlo@zancanaro.id.au>]

* gnu/services/certbot.scm (certbot-deploy-hook): Reload nginx.
* doc/guix.texi (Certificate services): Remove deploy-hook from example.

Change-Id: Ibb10481170a6fda7df72492072b939dd6a6ad176
---

I've pulled the nginx reloading into the regular deployment hook
here. I also removed the explicit deploy hook in the documentation,
because that is now the default behaviour.
