[github-actions]

Automated translation update from main branch push.

Note

Low Risk
Cosmetic documentation formatting only; no behavioral, API, or translated content changes in the diff.

Overview
Automated sync from main that only adjusts English MDX frontmatter and whitespace—no body copy or SEO text changes.

platform/data-sync.mdx, platform/environments.mdx, and platform/multi-tenancy.mdx now break long description and og:description values across multiple YAML lines (same wording as before). admin-api/authentication.mdx drops a single blank line immediately after the closing --- of the frontmatter.
