title: Add custom category using categories json file is not working . I am using allure 2.6 command line tool
body: <p>I created a categories json file with the following format:</p>
  
  <pre><code>[
    {
      "name": "Iored tests", 
      "matchedStatuses": ["skipped"] 
    },
    {
      "name": "Inructure problems",
      "matchedStatuses": ["broken", "failed"]
      "messageRegex": ".*bye-bye.*", 
    },
    {
      "name": "Outed tests",
      "matchedStatuses": ["broken"]
      "traceRegex": ".*FileNotFoundException.*", 
    },
    {
      "name": "Prot defects",
      "matchedStatuses": ["failed"]
    },
    {
      "name": "Tst defects",
      "matchedStatuses": ["broken"]
    }
  ]
  </code></pre>
  
  <p>and added this file to the allure-results folder and generate the report using allure generate command, but still, the generated reports show the default product categories.</p>
  
  <p>Please let me know if I am missing anything?</p>
