Unescaped translations are not flagged by 'HM' standards

Unescaped output from WordPress translation functions is not being flagged by the full HM standards checks.

The `HM-Minimum` standard allows the use of unescaped translation functions (see [HM-Minimum/ruleset.xml#L57-L66](https://github.com/humanmade/coding-standards/blob/f73d9dc587242fa2dbe3f1889ee3cfea17afc13a/HM-Minimum/ruleset.xml#L57-L66)). The minimum standards are then imported into `HM` standards ([HM/ruleset.xml#L12-L13](https://github.com/humanmade/coding-standards/blob/f73d9dc587242fa2dbe3f1889ee3cfea17afc13a/HM/ruleset.xml#L12-L13)), but there are no other rules in the `HM` standard that check the output of these functions is escaped.

The following code should pass `HM-Minimum`, but fail `HM`. Currently, it passes both.

```
echo __( 'This should error', 'err' );
```
