Don't need escape in rich text field

[mantaroh]

Describe the bug

If we have the following rich text field, Spear generate the linebreak character as \\r\\n.

<code>
  <ul>
   <li cms-loop cms-content-type="demo">
     <h1>{%= demo_[フィールドID1] %}</h1>
      <p>{%= demo_[フィールドID2] %}</p>
    <li>
  <ul>
</code>

Spear generate the following code;

<code>&lt;ul&gt;\\r\\n  &lt;li cms-loop cms-content-type=\"demo\"&gt;\\r\\n    &lt;h1&gt;{%= demo_[フィールドID1] %}&lt;/h1&gt;\\r\\n    &lt;p&gt;{%= demo_[フィールドID2] %}&lt;/p&gt;\\r\\n    &lt;img data-src=\"{%= v3demo-site-logo_[フィールドID3] %}\"&gt;\\r\\n  &lt;/li&gt;\\r\\n&lt;/ul&gt;\\r\\n</code>

The generated code use escaped line break (\r\n). So this HTML show the \r\n character.

To Reproduce

Expected behavior
