[8.x] Remove invalid docblock

[jrmajor]

Introduced in #37022.

Now when I call $someModel->restore(), PHPStan uses this docblock:

framework/src/Illuminate/Database/Eloquent/SoftDeletes.php

Line 9 in 68a269a

* @method static static|\Illuminate\Database\Eloquent\Builder|\Illuminate\Database\Query\Builder restore()

Instead of the correct one:

framework/src/Illuminate/Database/Eloquent/SoftDeletes.php

Lines 102 to 107 in 68a269a

	/**
	* Restore a soft-deleted model instance.
	*
	* @return bool|null
	*/
	public function restore()

PhpStorm also complains about that:
