FEATURE - Introduce SAP Help Portal (Documentation) tab

[cjbernal]

As a developer using Knowledge Hub,
I want to be able to search official SAP product documentation (help.sap.com),
so that I can learn more about a given product or find code snippets that will help me implement some sort of functionality in my project.

Description

This will create additional value for developers, who may need more technical help with their project. While blogs and tutorials are good for high level knowledge, including product documentation will allow users to access deeper levels of information.

Technical Design

What modules need to be created or enhanced?
How would the functionality be exposed and how can it be consumed?

Acceptance Criteria

GivenWhenThen format (https://martinfowler.com/bliki/GivenWhenThen.html)

Given I have the Knowledge Hub Documentation tab open ...
when I use the search bar ...
then Knowledge Hub will aggregate related results from help.sap.com.

Notes

help.sap.com currently allows global search for all documentation -- we should check if there is an API available to use to tie it into KH: https://help.sap.com/docs/

In order to streamline the search experience, we should try to create a similar experience to the Search Results page rather than the initial search.

Currently available filters are Product, Format, and Language. There is also an advanced search feature, but this can be pursued in another ticket. This ticket is concerned with allowing users to access SAP documentation on help.sap.com and perform as quick search.
