Update make production

[joshdentremont]

added commands to create drupal database and modify settings.php before running drush site install

[joshdentremont]

Before I added this line, make production was failing with:

docker compose exec -T drupal with-contenv bash -lc "drush si -y --existing-config minimal --account-pass 'XCIs6LUzks1MFwwU2WlFs1KDiOpz1gCsiDtNr8aAAqBQ9mjV'"

 You are about to:
 * Create a sites/default/settings.php file
 * CREATE the 'drupal' database.

 // Do you want to continue?: yes.

 [warning] Failed to drop or create the database. Do it yourself before installing. ERROR 2002 (HY000): Can't connect to server on '127.0.0.1' (115)


In SiteInstallCommands.php line 88:

  Existing config directory  not found

So I think it couldn't find the config/sync directory because it was not being specified in settings.php.

For testing you should be able to run make production without this PR and it should throw a similar error. With this PR it should create the site successfully.

I tested following the instructions for installing a production server and it worked.
