Move ApolloServerPluginLandingPageGraphQLPlayground to new package (#…

…6817) GraphQL Playground was unmaintained when we released Apollo Server 3, and the Apollo Server team has had to put significant work into fixing security issues in GraphQL Playground. While we will still publish a landing page plugin to enable folks upgrading from AS2 to not have to immediately retrain their users on how to use Apollo Sandbox or another interface, we remove it from the main `@apollo/server` package and move it to its own `@apollo/server-plugin-landing-page-graphql-playground` package. This lets us remove the Playground HTML package's dependencies (like `xss`) from Apollo Server's main package. Fixes #6109.

+# GraphQL Playground plugin
+
+This is a plugin for Apollo Server 4 that makes your GraphQL server serve the [GraphQL Playground IDE](https://github.com/graphql/graphql-playground) as a landing page.
+
+GraphQL Playground was the only landing page available for Apollo Server 2. The GraphQL Playground project is officially [retired](https://github.com/graphql/graphql-playground/issues/1143) and we do not recommend its continued use. We recommend Apollo Server 4's default landing page, which serves the similar but actively maintained [Apollo Sandbox](https://www.apollographql.com/docs/studio/explorer/sandbox/), or a custom landing page.
+
+To help developers migrating from Apollo Server 2, we do still provide a landing page plugin that allows you to use GraphQL Playground with Apollo Server. In Apollo Server 3, that plugin is distributed as part of the `apollo-server-core` package. In Apollo Server 4, that plugin is distributed separately in this package.
+
+To use GraphQL Playground with Apollo Server 4, first `npm install @apollo/server-plugin-landing-page-graphql-playground`, and then:
+
+```ts
+import { ApolloServer } from '@apollo/server';
+import { ApolloServerPluginLandingPageGraphQLPlayground } from '@apollo/server-plugin-landing-page-graphql-playground';
+
+const server = new ApolloServer({
+  plugins: [ApolloServerPluginLandingPageGraphQLPlayground()],
+  // ... other options ...
+});
+```
+
+Note that this will serve GraphQL Playground unconditionally. If you would prefer to only serve it when not in production, you can use `process.env.NODE_ENV` to determine whether to include the plugin in the `plugins` option yourself.
