Add WP Playground live preview integration #79
Description
What problem does this address?
Enable plugin testing with WordPress Playground.
What is your proposed solution?
So that folks finding the plugin at its future location at https://wordpress.org/plugins/ai can benefit from the WordPress Playground "Live Preview" option as well as providing a similar option here in the GitHub repo, let's look to do the following:
- add a blueprints.json file to the repo including any sample post/page and media to support a decent test experience (note that if the test data would help with the Playground test link on PRs that we should look to get that added into that GH action as well)
- add a "WordPress Playground Demo" badge at the top of the README.md file (see example here)
- once the plugin is published/live on WPORG, go through the steps to enable the "Live Preview" option there
