Update Playground integration

[jeffpaul]

Is your enhancement related to a problem? Please describe.

TLDR; Building upon the work in #814, we need to update our codebase to replace the deprecated pluginZipFile attribute with the recommended pluginData attribute when installing plugins in the WordPress Playground environment.

The longer part:
The WordPress Playground has deprecated the pluginZipFile attribute in favor of pluginData for specifying plugin installations in blueprints. Detailed information about this update can be found in the WordPress Playground API documentation. We'll want to update all instances in our code where pluginZipFile is used to pluginData. This involves modifying our blueprint configurations to ensure compatibility with the current WordPress Playground standards.

We already use pluginData in our installPlugin step so I don't see any update needed here
