[bug#77204] [PATCH 1/3] services: dnsmasq: Provide shepherd-provision and shepherd-requirement fields.

[Alexey Abramov]

* doc/guix.texi: Document the change.
* gnu/services/dns.scm (<dnsmasq-configuration>)[provision]: Rename the field to
[shepherd-provision] for consistency with other services.
* gnu/services/dns.scm (<dnsmasq-configuration>)[shepherd-requirement]: New 
field.
* gnu/services/dns.scm (dnsmasq-shepherd-service): Use newly-created fields.
