ERROR: column "__soft_deleted" does not exist when 'soft_delete' => true in scout config

(This might very well be related to #184, but since the latter is 2 years old, I don't want to revive it.)

Basically with this setup:

teamtnt/laravel-scout-tntsearch-driver v11.2.0
laravel/scout v8.6.1
laravel/framework v8.38.0
PHP 8.0.0rc1
'soft_delete' => true in config/scout.php

A search would result in an "undefined column" error e.g.,

 [2021-04-27 12:14:04] local.ERROR: 192.168.10.1 - 43ce52b1-7c08-4837-a5be-08eb717d66b4 2021-04-27T12:14:04.    739131Z GET /admin/companies/search?term=foo&_type=query&q=foo HTTP/2.0 - - {"message":"SQLSTATE[42703]:       Undefined column: 7 ERROR:  column \"__soft_deleted\" does not exist

                                         ^ (SQL: select * from \"companies\" where \"__soft_deleted\" = 0 and   \"companies\".\"id\" in (73000167-f69f-4389-8150-c1ec9ba3ee17))"}

Is this a bug or just something I'm not aware of?
