Fix RSS feed XML parsing error

This PR fixes the XML parsing error occurring in the RSS feed.

The issue happens because post.content contains HTML characters such as &, <, and > which can break XML parsing even after applying xml_escape. When the feed is generated, these characters sometimes cause the error:

xmlParseEntityRef: no name

To resolve this, the post content is wrapped inside a CDATA section. CDATA allows raw HTML content to be included without breaking the XML structure.

Changes made

• Replaced:
  <description>{{ post.content | xml_escape }}</description>

• With:
  <description><![CDATA[{{ post.content }}]]></description>

This ensures that HTML inside blog posts does not cause XML parsing errors in the RSS feed.

Fixes the issue related to RSS feed parsing.
