Password Rules Validation Tool provides invalid examples when multiple digits are required

I'm attempting to validate a rule at the [tool linked in the documentation](https://developer.apple.com/password-rules/) but it minimally doesn't seem to be working correctly for rules that require multiple digits. At first I wasn't sure if maybe this type of rule just wasn't supported, but I see existing quirks specify it so believe it to be an issue with the tool.

I've been supplying this rule:
```
required: lower, upper;
required: digit;
required: digit;
required: [-];
```

And got back these examples:
```
RJt-k1f-DGf-nIh <-- only has a single digit '1'
kSA-0Rb-asB-Cze <-- only has a single digit '0'
Ben-b6l-roL-37u <-- does have multiple digits
```

Start with the password-rules validation tool linked from the documentation and reproduce the supplied rule requiring two digits. Compare its generated examples with the rule’s requirements, including the three examples in this report. Done means every returned example contains multiple digits while still satisfying the other stated requirements.
