WHAT
The changes introduced by MGDAPI-3652 result in building a new file-based version of the catalog images for CRO. This is done by iterating over each of the bundles in turn to generate the channel entries with replaces/skip versions. MGDAPI-4119 replaced this to render from the latest index, however the historical bundles are no longer required in the CRO repo (as they are effectively retained through git history).

HOW
Modify the gen-csv script to build bundles at bundles/ instead of bundles/$VERSION

Modify create-olm-bundles script to render the latest bundle from this single manifest directory

Remove historical bundles from CRO repository - we no longer need to maintain all of the bundle files and can maintain only this latest bundle.

Update README as there may be necessary changes for deploying / upgrading with OLM.

TESTS

• Check that regular upgrades work as intended
• Ensure that upgrades from a skip version work as intended
