Custom name for withResponsiveImages on addMediaCollection

[ghost]

Hi,

I'm not sure if this is a bug, but whenever I try to add responsive images like

public function registerMediaCollections(Media $media = null): void
{
    $this->addMediaCollection('banner')
        ->withResponsiveImages()
        ->singleFile();
}

And upload an image it will make a bunch of images like
/storage/app/public/{id}/responsive-images/{name}___media_library_original_{width}_{height}.{extension}.

Now I would like to change ___media_library_original_ to something else. I saw that it does work with conversionName.

So when you do

public function registerMediaCollections(Media $media = null): void
{
    $this->addMediaCollection('banner')
        ->singleFile();

    $this->addMediaConversion('responsive')
        ->withResponsiveImages();
}

It will generate another conversions folder with a single conversion file.
But also in /responsive-images it will generate both the responsive and media_library_original files.
So you'll have duplicated files.

It it supposed to work like this ? Shouldn't it only generate the
/storage/app/public/{id}/responsive-images/{name}___responsive_{width}_{height}.{extension}.
and not generate the
/storage/app/public/{id}/responsive-images/{name}___media_library_original_{width}_{height}.{extension}.
anymore ?

Or what's the correct way to achieve this.

I'd accept a PR (including tests) that fixes this.
