hybris Version Requirements are Incorrect on Data Hub Publication Grouping Handlers

The hybris version for Publication Grouping Handlers indicates hybris 5.5.0. This functionality actually requires hybris 5.5.1.

Can someone update this page to indicate the correct hybris version (5.5.1 and higher)?
