Set doc-scrape-example = true for recently merged example (#23230)

# Objective

- PR was merged recently that didn’t set doc-scrape-example to true

## Solution

Set it to true since the bug has been resolved. all examples can be
scraped now.

(At this point in time, all other examples are already set to true)
