fix: improve product availability check in algoliaLocalizedProduct.js

[htuzel]

What is Changed?

Updated the in_stock handler to utilize the ProductAvailabilityModel for better accuracy in determining product availability. The logic now checks the availability status directly for master products and variation groups, and retrieves the inventory record for other products to assess stock levels against the defined threshold.

Important Note

Note: Should be changed:

in_stock: {
    localized: false,
    variantAttribute: true,
}

to:

in_stock: {
    localized: false,
}

To update in_stock partially and move it to the record level.

The change is ok but I don't understand the use case. In the doc update, you write:

to update only stock and price attributes for each variant, move the in_stock and price attributes to the record level

But what do you plan to do with this information? Currently, we could improve the UI to only display variants that are in stock. With the info moved at the product-level, we will have to show all variants, even if they are out-of-stock.

Was there a request for this change?

Some clients who are using the base record model are keeping the in_stock attribute on the first level (not in variants), and they want to be able to update the in_stock attribute. I opened this ticket by discussing this with @matthias-meier-algolia a long time ago.
