[BUG] Tabbed sections - sequential display and wrong URL

[digitaldiina]

Bug overview

Description: Seems like we've forgotten to implement tabbed content sections #56 #60
Steps to reproduce: go to https://app-superoffice-docs-dev.azurewebsites.net/en/api/web-services/howto/company/create-contact
Expected result: Compare to https://docs.superoffice.com/en/api/netserver/web-services/howto/company/create-contact.html?tabs=rest
Actual result:

• all sections displayed at the same time, vertically, instead of as a group of tabs - this we can live with for a while, but
• docs-next produces urls like create-contact#tab/rest, while prod (docfx) gives create-contact.html?tabs=rest - will result in 404s on incoming links (worse)
