Fix grammatically incorrect variable name in getBlog

[Copilot]

Addresses review feedback from PR #138 to rename sortsBlogs to sortedBlogs in src/lib/getBlog.ts.

Changes

• Variable naming: Renamed sortsBlogs → sortedBlogs to correctly indicate the variable contains sorted results rather than suggesting an action

const getBlog = async () => {
  const blogs = await getCollection('blog');
  const sortedBlogs = blogs.sort((a, b) => {
    const dateA = new Date(a.data.pubDate).getTime();
    const dateB = new Date(b.data.pubDate).getTime();
    return dateB - dateA;
  });

  return sortedBlogs;
};
