Testing

Installed MAS 9.0.2 from v9-240827-amd64 catalog using CLI 11.1.3
Updated MAS to 9.0.10 with v9-250403-amd64 catalog using CLI 13.27.0-pre.mongo-upd-arm64
Observed mas update pipeline - mongodb task ran and updated mongodb from 6.0.12 to 7.0.12
Removed everything from cluster using mas uninstall

• This test shows that when mongodb ce installed on the cluster the mongodb task in the pipeline will update it as usual

Installed MAS 9.0.2 from v9-240827-amd64 catalog using CLI 11.1.3
Removed MongoDB CE from cluster and connected MAS to external MongoDB
Updated MAS to 9.0.10 with v9-250403-amd64 catalog using CLI 13.27.0-pre.mongo-upd-arm64
Observed mas update pipeline - mongodb task did not update mongodb because we pass in none as mongodb_action

• This test shows that when mongodb ce is not on the cluster the mongodb task does not fail in the pipeline nor will it do anything as expected
