resolve: add missing ServiceNotProvided error to Varlink IDL (#40858)

The error is emitted by `vl_method_resolve_service_complete()` when an
SRV record with a root domain hostname is found, indicating the service
is explicitly not offered on the queried domain (RFC 2782 Usage Rules),

but was not declared in the `io.systemd.Resolve` interface definition.

Follow-up for 3d8f2c14641f840e0ad6380ec3e773bbb40e67df.
