seo(redirects): /sitemap_index.xml -> /sitemap/index.xml

[vfanucci]

Summary

• Add a 301 redirect from the legacy /sitemap_index.xml URL to the canonical /sitemap/index.xml.
• Avoids 404s for external links, crawlers and any cached references still pointing at the old path.

Test plan

• After deploy, curl -I https://kestra.io/sitemap_index.xml returns a 301 to /sitemap/index.xml
• https://kestra.io/sitemap/index.xml keeps serving the sitemap index unchanged

[vfanucci]

IA crawlers naturally fetch the sitemap here /sitemap_index.xml with the redirection we avoid 404 and better readility
