Wrong status report descriptions

Problem/Motivation

On the Status report page, some insights show errors or information about the problem inside the description wrapper.
The description wrapper should only be used to describe the problem, as help text. It should not be used to show the error or the current status.

<div class="system-status-report__entry__value"> The following entities have bundles that are not used.
  <div class="description">
    <dt>
      <a href="/admin/reports/xray-audit/content-metric/paragraphs-count-type">Paragraphs</a>:
    </dt>
    <dd>Moments, Featured products</dd>
    <dt>
      <a href="/admin/reports/xray-audit/content-metric/taxonomy-term-count-type">Vocabulary</a>:
    </dt>
    <dd>intent_type, product_tags, recipe_category, tags</dd>
  </div>
</div>

Steps to reproduce

1. Enable the xray_audit_insight module.
2. Go to the Status report page (/admin/reports/status).
3. Check one of the following insights:
   • Xray Audit: Entities bundles usage
   • Xray Audit: Modules not enabled
   • Xray Audit: Views cache
   • Xray Audit: Admin views accessible by anonymous
4. Check that the information about the problem (the list of affected items, or the status message) appears inside the description wrapper:
   <div class="description">

Proposed resolution

Keep the description wrapper only as help text for the user to understand the problem.
