Fixes #6204

The RSS feed was using .Lastmod (from Git commit info) for both the pubDate tag and the chronological sorting of items. This meant that any minor edit to an existing blog post caused it to jump to the top of the feed and appear as a new publication to RSS readers and bots.

This PR updates layouts/rss.xml to use .Date (the original publication date from the front matter) instead of .Lastmod. This ensures the RSS feed correctly reflects the original publication date and prevents unnecessary reposting of updated content.

@LoveChauhan-18, thank you for your contribution!

I haven't had a chance to review the changes in rss.xml yet, but I don't think the .agents folder was supposed to be included in this PR.

Could you please check that?

Hi @vitorvasc,

Thank you for the review! You're correct—the .agents folder was included by mistake. I've now removed it from the PR, so only the intended changes to layouts/rss.xml remain.

I've also synchronized the branch with the latest upstream/main and fixed the formatting issues (line endings) that were causing the "FILE FORMAT" check to fail. Everything should be green and clean now.

Could you please take another look?
