Document workflow types and PR actions

[mintlify]

Summary

Adds documentation for recently-shipped workflow capabilities:

• Workflow types: a new optional field on workflows that selects a built-in, maintained prompt for a common documentation task. Users can pick from Changelog, Source code agent, Translations, Writing style, Typo check, Broken link detection, and SEO metadata audit, or stay on Custom and write their own prompt. Each type is limited to one per deployment, and any prompt a user provides is appended to the built-in template for project-specific customization.
• Review a workflow run: two new per-instance actions in the dashboard that let users merge or close the pull request (or GitLab merge request) opened by a workflow run without leaving Mintlify. Both actions support GitHub and GitLab and honor the same auth and permission model as auto-merge.

Changes

• agent/workflows.mdx:
  • Added a Type row to the configuration table linking to the new section.
  • Added a Workflow types section with a table of built-in templates and guidance on extending them with custom instructions.
  • Added a Review a workflow run subsection under Manage workflows covering the new Merge and Close actions.

Note

Low Risk
Low risk: documentation-only updates that describe new workflow configuration options and dashboard actions, with no product code changes.

Overview
Adds docs for a new optional workflow Type field and a Workflow types section describing the built-in templates (and how to extend them with additional prompt instructions).

Also documents Review a workflow run actions in the dashboard, explaining how to merge or close the PR/MR for a workflow run (including GitHub/GitLab permission notes).
