Previewing WordPress Pull Requests requires either a local development setup or a staging setup.

WordPress developers often use either a staging environment that can only run a single branch at a time, or no staging environment at all. This makes testing and team workflows difficult.

Providing an easy way to preview pull requests using Playground would alleviate that burden, catalyze more reviews across the ecosystem, and make calls for testing easier.

For example, a Playground link was used in "Help test the Font Library" post. cc @ironprogrammer
