Fix breadcrumbs for "products" pages

[JeffLowe]

Breadcrumbs currently do not show for any of the product pages. Update site to ensure that breadcrumbs work /display for these pages.

• [ ] update breadcrumbs to reflect the correct product page
• [ ] update the tab title (currently shows "About - web3.storage"

We should likely show the following in the breadcrumbs:

• "Home / Products / Web3.Storage" (when on https://web3.storage/products/web3storage/ )
• "Home / Products / w3name" (when on https://web3.storage/products/w3name/ )
• "Home / Products / w3link" (when on https://web3.storage/products/w3link/ )
