Fix for phpstan

[erikn69]

With @mixin \Spatie\Image\Manipulations for phpstan the magic methods returns \Spatie\Image\Manipulations but the real return is \Spatie\Image\Image

So when concatenating phpstan give you
Call to an undefined method Spatie\Image\Manipulations::save()

Is there a better way to fix that??

Maybe addig a dumb @method static void save(string $outputPath = '') on \Spatie\Image\Manipulations?

Thanks for your work on this!

I'm going to pass on this one for now.

We'll soon create a new major version of this package that drop the dependency on intervention/image and league/glide.
