The purpose of this task is to create unit tests for the following files so the unit test coverage is as high as reasonably possible (aiming for at least 75% line coverage), but higher than 20% line coverage.

Out-of-scope: Any clean-up or modification to the component or file itself—only the unit tests will be changed.

NOTE: There are no changes to the functionality, behavior, or visual changes, no testing beyond passing unit tests is required.

Files to have unit tests written for:

• /src/components/clusters/wizards/rosa/ClusterRolesScreen/CustomOperatorRoleNames.jsx
• src/components/clusters/common/ScaleSection/MachineTypeSelection/machineTypeSelectionHelper.test.ts
• /src/components/clusters/wizards/rosa/UpdatesScreen/UpdatesScreen.jsx
• /src/components/clusters/wizards/rosa/VPCScreen/VPCScreen.tsx
• /src/components/clusters/wizards/rosa/common/BackToAssociateAwsAccountLink.jsx
