[bug#28269] [PATCH] services: web: Fix nginx-service-type's ‘file’ procedure.

[Tobias Geerinckx-Rice <me@tobias.gr>]

* gnu/services/web.scm (nginx-activation, nginx-shepherd-service): Replace
references to non-existent ‘config-file’ with ‘file’.
* doc/guix.texi (Web Services): Likewise.
---

Guix,

This fixes using a ‘native’ nginx configuration file under GuixSD, so
I can finally update my web server.

I wasn't sure whether to keep the procedure as ‘file’, and fix all
references to it, or rename it to ‘configuration-file’. Then Andreas'
commit 036cd84 to maintenance rolledin which I took as a pragmatic
endorsement of ‘file’.

I don't have a strong preference either way. Both are better than the
old ‘config-file’, and we have no backwards compatibility to care about.

Kind regards,

T G-R
