Settings in `GCP_STORAGE_EXTRA_STORES` not being applied to stores

Bug report

What is the current behavior?

I'm using the GCP_STORAGE_EXTRA_STORES option in a django app to allow image uploads to a public bucket from an ImageField. As it's a public bucket, I'd like the URL returned for the images to be an unsigned public URL. I set up the option like this:

GCP_STORAGE_EXTRA_STORES = {
    "store-name": {
        "bucket_name": "bucket-name",
        "default_acl": "publicRead",
        "querystring_auth": False,
    },
}

and the image field like this:

 image = ImageField(
    upload_to="directory-name",
    storage=GoogleCloudStorage(store_key="store-name"),
    blank=True,
    null=True,
)

but I'm still getting signed URLs returned for the images uploaded.

As a workaround, I've had to manually add the options to the image field like this:

 image = ImageField(
    upload_to="user_images",
    storage=GoogleCloudStorage(store_key="profile_images", default_acl=None, querystring_auth=False),
    blank=True,
    null=True,
)

What is the expected behavior?

I should be able to set the options in the django settings files for the extra store and get public unsigned URLs returned for images uploaded to the image field. I shouldn't have to manually set the options in the model that the image field belongs to.
