JSON-stringify accessibility violations before console-logging them

[acelaya]

By doing a simple console log, accessibility violations were being printed like this:

ERROR: 'axe-core violation', Object{id: 'aria-valid-attr-value', impact: 'critical', tags: ['cat.aria', 'wcag2a', 'wcag412', 'EN-301-549', 'EN-9.4.1.2'], description: 'Ensures all ARIA attributes have valid values', help: 'ARIA attributes must conform to valid values', helpUrl: 'https://dequeuniversity.com/rules/axe/4.8/aria-valid-attr-value?application=axeAPI', nodes: [Object{any: ..., all: ..., none: ..., impact: ..., html: ..., target: ..., failureSummary: ...}]}

With this new approach they are printed on a more human-friendly way in which errors can be inspected and more easily interpreted:

  "tags": [
