userid-validation: reduce email noise from Jenkins

Jenkins userid-validation review causes a lot of low value emails.
Leverage the `--notify=NONE` option on the typical review indications
to reduce these emails.

```
 --notify (-n) [NONE | OWNER |          : Who to send email notifications to
 OWNER_REVIEWERS | ALL]                   after the review is stored.
```
