Document auto-generated page title fallback

[mintlify-development]

Summary

• Documents that the title field in page frontmatter is now optional
• When omitted, the title is auto-generated from the file path (e.g., getting-started.md → "Getting started")
• Updates the Pages documentation to reflect this behavior change from mintlify/mint#6459

---

Note

Low Risk
Low risk documentation-only change that updates frontmatter guidance and adds an explanatory example; no runtime behavior is modified.

Overview
Updates organize/pages.mdx to make the title frontmatter field optional and documents the new fallback behavior: when title is omitted, Mintlify auto-generates it from the page’s file path (with a concrete example).
