Move developer.wordpress.org/playground to wordpress.org/playground

[adamziel]

As discussed in https://github.com/WordPress/wordpress-playground/issues/728, a Playground overview page makes a lot more sense under the top-level wordpress.org site. To quote @courtneyr-dev:

Given the general introductory nature of the content currently at https://developer.wordpress.org/playground, When I think of where to find such introductory information, Then I expect it to be located at a top-level domain such as https://WordPress.org/Playground, And I would appreciate a direct link from the main navigation menu to discover what WordPress Playground is all about easily.

Let's make sure it's available on https://wordpress.org/Playground. Technically that could mean either moving developer.wordpress.org/playground there, or creating a new site and populating it with the same content.

Once that's in place, the next step would be to ship the documentation on the developer.wp.org site. I created a separate issue to track it here: https://github.com/WordPress/wporg-developer/issues/412

@StevenDufresne suggested opening a ticket here to make that happen.

@adamziel @ @courtneyr-dev

Thinking more about this, how many links are in the wild suggesting //developer.wordpress.org/playground is the playground itself?

How are we going to cater to those users?

Add something in the docs?

@StevenDufresne Yes, updating the docs seems like the best way forward. I'll add a note at the top along the lines of:

Looking for the official Playground website? Go to wp.org/playground

How about this? https://github.com/WordPress/wordpress-playground/pull/866
