Add June 2026 external blog redirects for DevBlogs and Teams Blog posts

[Copilot]

This updates the Teams SDK blog index to include two requested external posts so they appear in our blog feed and route out correctly. It adds one DevBlogs post and one TechCommunity Teams Blog post using the existing external-redirect pattern.

• External redirect entries

  • Added new blog redirect at teams.md/blog/2026-06-02-build-collaborative-agents-where-work-happens/index.mdx
  • Added new blog redirect at teams.md/blog/2026-06-02-whats-new-in-microsoft-teams--may-2026---build-edition/index.mdx

• Slug-to-URL mapping

  • Updated teams.md/src/data/externalBlogUrls.ts with both new slugs so sidebar/link resolution recognizes them as external links

• Redirect format used

  ---
  slug: build-collaborative-agents-where-work-happens
  external_url: https://devblogs.microsoft.com/microsoft365dev/build-collaborative-agents-where-work-happens/
  ---
  import ExternalRedirect from '@site/src/components/ExternalRedirect';
  <ExternalRedirect to="https://devblogs.microsoft.com/microsoft365dev/build-collaborative-agents-where-work-happens/" />

Addressed in commit 21941fb.

• Updated both new posts with the requested author names
• Restored teams.md/static/missing-pages.json to undo the unrelated removal
