fix: add @primary annotation for DefaultConstraintValidatorFactory (#370

)

A `ConstraintValidationFactory` aws added to Micronaut Validation in [PR 288](micronaut-projects/micronaut-validation#288). This PR sets the Hibernate Validator as the primary `ConstraintValidatorFactory` in case there are many in the classpath and avoids:

```
Caused by: io.micronaut.context.exceptions.NonUniqueBeanException: Multiple possible bean candidates found: [DefaultInternalConstraintValidatorFactory, DefaultConstraintValidatorFactory]
```

see: micronaut-projects/micronaut-sql#1266
