Incomplete examples in API docs for the download process plugin

There are no core migrations that explicitly use the download process plugin, but the file_copy plugin uses it for remote files:

    // If the source path or URI represents a remote resource, delegate to the
    // download plugin.
    if (!$this->isLocalUri($source)) {
      return $this->downloadPlugin->transform($value, $migrate_executable, $row, $destination_property);
    }

So we can use basically the same sample code for both.

Since we already have two examples, we can use one of them for a more complete example, creating a file entity, based on the d7_file migration.

This issue is ready for review.

Change makes sense. Looked at the d7_file.yml for file_copy and see the same.

Thanks for reviewing!

NW for above nitpick. Thanks!

Thanks for catching that. I accepted the suggestion on the MR.

My mistake! Looks good now

Committed to 11.x, and backported to 10.1.x as a patch-eligible documentation improvement. Thanks!
