Alert Manager definition list error

Description of problem:
The alert manager is missing a <dl> in the definition list structure under the Alert Routing section. The parent dl element ensures the list follows the proper hierarchy. This help screen reader users know what they are listening to, and what to expect as they listen to definition lists with regard to the organizational relationship of parent and child items. (https://dequeuniversity.com/rules/axe/3.5/dlitem?application=AxeChrome)

It currently has the following axe error: 
{
    "data": null,
    "id": "dlitem",
    "impact": "serious",
    "message": "Description list item does not have a <dl> parent element",
    "relatedNodes": [
      {
        "html": "<dt>Group By</dt>"
      }
    ]
  },
  {
    "data": null,
    "id": "dlitem",
