Docs: Correct documentation for the `in_plugin_update_message-{$file}` filter.

The `$response` parameter is an object, not an array.

This is a minor inconsistency with the corresponding `in_theme_update_message-{$theme_key}` action for themes, where the `$response` parameter is an array.

For backward compatibility, it is safer not to change the parameter type at this point, but to make sure the documentation is correct.

Follow-up to [11193], [16141], [26540].
