✨ Add CreateNodeFromContentOptions to insertContent

[castroCrea]

insertContent for HTML with table on it, doesn't work well due to preserveWhitespace: 'full', when false it work well.

what I have done

• Add the possibility to make it false.
• Update the doc

compare to

for this HTML

<table style="width:100%">
  <tr>
    <th>Firstname</th>
    <th>Lastname</th> 
    <th>Age</th>
  </tr>
  <tr>
    <td>Jill</td>
    <td>Smith</td>
    <td>50</td>
  </tr>
  <tr>
    <td>Eve</td>
    <td>Jackson</td>
    <td>94</td>
  </tr>
  <tr>
    <td>John</td>
    <td>Doe</td>
    <td>80</td>
  </tr>
</table>
