This bug is annoying. Everytime i generate the model phpdocs i just replace null|null to null in my IDE

I fixed this bug on my local ModelsCommand.

Everywhere i saw something like:

if ($nullable) {
      $newType .= '|null';
}

I changed it with:

if ($nullable && !str_ends_with($newType, '|null')) {
     $newType .= '|null';
}

This was fixed in the latest release; I saw also in my projects the "double null" disappear.
