Add ability to print warnings when `failOnViolation: true` and `violationSeverity: error`

### New feature, improvement proposal

#### Currently

When there are errors and warnings, only errors are logged

#### Desired

Warnings should be logged, too

#### Current workaround

Add `consoleOutput: true`. However, this has the following undesired issues:

- No console format/colors
- It shows full path instead of relative path
- Errors appear again
