Migrate enzyme tests to @testing-library/react

[petermakowski]

We still have a few enzyme tests remaining that should be migrated to @testing-library/react.

This is blocking React v18 upgrade as enzyme doesn't support React v18

Tasks from below can be converted to Issues as marked as completed once done.

List of enzyme tests to migrate

• Tabs/Tabs.test.tsx
• AccordionSection/AccordionSection.test.tsx
• Pagination/Pagination.test.tsx
• ActionButton/ActionButton.test.tsx
• Form/Form.test.tsx
• Tooltip/Tooltip.test.tsx
• Strip/Strip.test.tsx

Once all the above is complete, we can remove enzyme from react-components
