docs: move redirects

[Meschreiber]

The docs team is centralizing redirects from _redirects files into the docs platform repository. (See https://github.com/apollographql/docs-rewrite/pull/370)

Docs in external repositories can still add redirects in page frontmatter like so:

---
title: Apollo GraphOS Platform
description: The GraphQL API Platform
redirectFrom:
    - /intro/platform
    - /graphos
    - /federation/managed-federation/overview
---

Redirects in a page's frontmatter take precedence over redirects in the _redirects file but flag a warning.
