[Documentation] "Load an older WordPress version" example throws error in Playground.

[nikunj8866]

Issue Description

On the examples documentation page, the Load an older WordPress version section includes a "Try it Out" button that leads to a broken Playground instance.

Clicking the button results in an error screen instead of loading the intended older WordPress version.

Additionally, attempting to copy and run the associated blueprint JSON manually inside the Playground also results in an error.
