Update sceditor version

[chrisdo1]

When WYSIWYG is enabled for text fields, the sceditor loads. Unforunately, the height of the embedded iframe is set using inline styles and hides content from the editor.

Pattern-kit is loading a fairly old version of the sceditor (v1.4.3)
Sceditor is currently at 3.1.1 https://www.sceditor.com/

These three files need to be updated in resources/templates/_pattern-kit-app.twig
<script src="https://cdn.jsdelivr.net/npm/sceditor@3.1.1/minified/jquery.sceditor.bbcode.min.js"></script>
<script src="https://cdn.jsdelivr.net/npm/sceditor@3.1.1/minified/jquery.sceditor.xhtml.min.js"></script>

Updating those three files fixes the bug
