Subject: [PATCH] Add RSS Browser Preview

This implments https://codeberg.org/benjaminhollon/benjaminhollon.com/src/branch/main/assets/xsl/rss.xsl, and is a featured RSS Preview... this does not render with the rest of the site, and is instead a static XSL file to avoid further complexity, this is due to the nature of XSL, and not properly parasing HTML into here, thus the footer is not featured, nor is the header. This does however work for most purposes
