fix: update community URLs and add layout to community pages (#471)

On-behalf-of: Gerald Morrison (SAP) <[email protected]>

<!-- markdownlint-disable MD041 -->
#### What this PR does / why we need it
re-introduce permalinks for the community page. These got lost, because
we introduced a special rendering for the community side to make it
centric, instead of attached to the left ,margin.
