fix: remove year grouping from blog sidebar Recent Posts

[Copilot]

The "Recent posts" sidebar on blog post pages grouped entries under year headings (e.g. "2026"), cluttering the sidebar. Posts should be shown in a flat descending list with no year separators.

Changes Made

• docusaurus.config.ts — added blog.sidebar.groupByYear: false to themeConfig:

blog: {
  sidebar: {
    groupByYear: false,
  },
},

Docusaurus defaults groupByYear to true; flipping it removes the year headings and renders a flat, newest-first list (descending order is already the Docusaurus default for sidebar items).

Type of Change

• New feature (e.g., new page, component, or functionality)
• Bug fix (non-breaking change that fixes an issue)
• UI/UX improvement (design, layout, or styling updates)
• Performance optimization (e.g., code splitting, caching)
• Documentation update (README, contribution guidelines, etc.)
• Other (please specify):

Dependencies

• No new dependencies.
