Support changes to Methods in ModelHooks for inheritance

[jenga201]

The ModelHooks in #945 look great.
I'm hoping support for Methods could be also added. (or maybe I'm generating these PHP docs wrong, I'm not sure)

I've added a PR #1198 to support my use case.

My use case is;

A CommonModel with some general scope(s) defined

class CommonModel extends Model
{
    public function scopeConnection($query, $connectionName): CommonModel
    {
        $this->setConnection($connectionName);
        return $this;
    }
}

A Model that extends this CommonModel

class MyModel extends CommonModel
{
    protected $table = 'mymodel';
}

The generated PHP docs look like;
@method static \Illuminate\Database\Eloquent\Builder|CommonModel connection($connectionName)
Changing this line to return MyModel will give my IDE the ability to use the scope as needed and still retain the correct properties.
@method static \Illuminate\Database\Eloquent\Builder|MyModel connection($connectionName)
