Add support for the WordPress.org plugin preview

[dkotter]

Description of the Change

WordPress.org recently launched support for plugin previews utilizing the WordPress Playground feature. Plugins wanting to take advantage of this need to opt in by setting up a blueprint.json file that configures how the preview should load. This PR adds in that file that does the following:

1. Sets up an environment running PHP 7.4 (our supported minimum) and the latest version of WordPress
2. Logs into the admin
3. Installs and activates the plugin
4. Sends the user to a post that has the Apple Maps block in place

Note that this PR is targeted to trunk so we can take advantage of our Plugin Asset Update Action to deploy these changes without having to push out a new release.

Also note once these changes are on .org, the preview button will need to be enabled in a test state. Once verified as working, we can enable it for all users.

How to test the Change

The WordPress Playground allows you to spin up a new environment directly through the URL, by going to https://playground.wordpress.net/# and pasting your JSON config after the #. In this case, the URL should be: https://playground.wordpress.net/#{%20%22$schema%22:%20%22https://playground.wordpress.net/blueprint-schema.json%22,%20%22landingPage%22:%20%22\/wp-admin\/post.php?post=6&action=edit%22,%20%22preferredVersions%22:%20{%20%22php%22:%20%227.4%22,%20%22wp%22:%20%22latest%22%20},%20%22phpExtensionBundles%22:%20[%22kitchen-sink%22],%20%22steps%22:%20[%20{%20%22step%22:%20%22login%22,%20%22username%22:%20%22admin%22,%20%22password%22:%20%22password%22%20},%20{%20%22step%22:%20%22installPlugin%22,%20%22pluginZipFile%22:%20{%20%22resource%22:%20%22wordpress.org\/plugins%22,%20%22slug%22:%20%22maps-block-apple%22%20},%20%22options%22:%20{%20%22activate%22:%20true%20}%20},%20{%20%22step%22:%20%22importFile%22,%20%22file%22:%20{%20%22resource%22:%20%22url%22,%20%22url%22:%20%22https:\/\/raw.githubusercontent.com\/10up\/maps-block-apple\/385fb9705624c2fe6822ac399ed08f09a5e80388\/.wordpress-org/blueprints\/demo-data.xml%22%20}%20}%20]%20}

@dkotter worth asking if you think it might be better to drop them into the editor with an empty Apple Maps block that they'll need to configure to test/demo?

Makes sense (though in testing, seems we have an over aggressive check for the credentials. I get the message Missing Private Key over and over as I try and edit a post with that block). The new test URL is https://playground.wordpress.net/#{%20%22$schema%22:%20%22https://playground.wordpress.net/blueprint-schema.json%22,%20%22landingPage%22:%20%22\/wp-admin\/post.php?post=6&action=edit%22,%20%22preferredVersions%22:%20{%20%22php%22:%20%227.4%22,%20%22wp%22:%20%22latest%22%20},%20%22phpExtensionBundles%22:%20[%22kitchen-sink%22],%20%22steps%22:%20[%20{%20%22step%22:%20%22login%22,%20%22username%22:%20%22admin%22,%20%22password%22:%20%22password%22%20},%20{%20%22step%22:%20%22installPlugin%22,%20%22pluginZipFile%22:%20{%20%22resource%22:%20%22wordpress.org\/plugins%22,%20%22slug%22:%20%22maps-block-apple%22%20},%20%22options%22:%20{%20%22activate%22:%20true%20}%20},%20{%20%22step%22:%20%22importFile%22,%20%22file%22:%20{%20%22resource%22:%20%22url%22,%20%22url%22:%20%22https:\/\/raw.githubusercontent.com\/10up\/maps-block-apple\/385fb9705624c2fe6822ac399ed08f09a5e80388\/.wordpress-org/blueprints\/demo-data.xml%22%20}%20}%20]%20}

@dkotter I see your comment on the Missing Private Key notifications... maybe we delay on checking there until someone clicks the Confirm MapKit Credentials button?

Yeah, seems we can handle this check a bit better, though that's not related specifically to this PR. I'd suggest we open a new issue to track that and can proceed here, assuming no other changes are needed

Looks good, thanks for getting this set up!
