[Forwardport] Fix sitemap grid render incorrect base urls for multiple stores

[nntoan]

Original Pull Request

#18000

Description

In Magento/Sitemap/Block/Adminhtml/Grid/Renderer/Link.php, we've created new instance for \Magento\Sitemap\Model\Sitemap. That lead to $sitemap->getStoreId() is NULL all the time, the sitemap.xml generated still using correct store id because of we load $sitemap instance from the collection which retrieve data directly from the database.

So to fix this issue, we should set the store id for the current sitemap object based on store id retrieved from the current row.

Fixed Issues (if relevant)
