fix: [] Fix Shopify not displaying missing SKUs for collections/products

[OriginalEXE]

Hello, this PR solves three issues:

1.) For collections preview we were fetching first 20 collections meaning that for stores with more than 20 collections the preview would break. I have increased that limit to 250 (max) as Shopify unfortunately does not support fetching multiple collections by ids

2.) This PR also makes sure that missing collections/products (if they are deleted for example) still show up in the interface. This was always the case for product variants, but I missed adding it for products/collections.

3.) I have also amended the ecommerce-app-base to display the correct sku type in the "missing" tag.

Thanks :)

not sure I understand the reason for this change

Hey John, without that code, when we pass a product that has no image (happens when for example the sku can no longer be found in the shop), the component unnecessarily renders an img with an empty src, only to then immediately error and set this boolean to true. By immediately setting it to true, we prevent that unnecessary dance.

Just a small optimization, but not important if you think it makes the code harder to read.

I might instead leave this as is, make the following change below - because it makes a bit more sense to me, and avoids imageHasErrored actually meaning two different things. I leave it up to you though :)

          {!product.image || imageHasErrored ? (
            <div className={styles.errorImage}>
              <Icon icon={productIsMissing ? 'ErrorCircle' : 'Asset'} />
            </div>
          ) : (
            <div className={styles.imageWrapper(imageHasLoaded)}>
              <img
                style={{ display: imageHasLoaded ? 'block' : 'none' }}
                onLoad={() => setImageLoaded(true)}
                onError={() => setImageHasErrored(true)}
                src={product.image}
                alt={product.name}
                data-test-id="image"
              />
            </div>
          )}

A great suggestion, implemented :)
