Add Products page with pagination.

[imranhsayed]

Add Products page with pagination. ( url: /products/ ).
We need to discuss whether we would want to use JS solution for pagination or use https://github.com/valu-digital/wp-graphql-offset-pagination for pagination as we need this feature to work offline.
We should be able to cache the page/1, page/2 etc.

Hi @imranhsayed, any decisions/updates on the pagination part?
