BUG: Render invalid json when preview list

[zipofar]

Render invalid json:
preview list --output=json

{
             :id => 2316,
     :created_at => "2022-09-02T01:44:57.812Z",
     :updated_at => "2022-09-02T10:57:03.616Z",
          :state => "active",
    :preview_url => "deployment-2316-make-test-22je.app.qa-gke.uffizzi.com",
       :metadata => {
        :labels => {
            :repo => "my-repo-1"
        }
    },
    :deployed_by => {
        :email => "demid.filippov@dualbootpartners.com"
    }
}
