Purpose
Re-enable the ability to select sort order for Software Catalog items so that users can choose their sort ordering.

Background
When this feature request was implemented with this PR, the Software Catalog list results switched from a default alphabetical listing to a relevance based ordering with Red Hat Provider prioritization, to determine item ranking for lists.

At the same time OperatorHub was moved from an independent catalog with its own search, into being a part of the overall Software Catalog. So now everything uses a unified single search input and filter by categories UI. One difference, between the two catalogs was the Software Catalog included a sort select element with the options of A-Z or Z-A sort order and OperatorHub did not.

In order to get https://github.com/openshift/console/pull/15322 merged the decision was made to disable the Software Catalog catalogSortItems. Then re-enable in a follow-up.
