Related to #1110
Related to #726

Description of the change:

• Remove unused enzyme-related dependencies.
• Explicitly requests react-test-renderer package (v17.0.2). Downgrade @types/react-test-renderer to match.
• Move runtime deps to their correct sections (i.e. dependencies).
• Upgrade eslint-plugin-unused-imports to 3.0.0 to match dep requirements. @patternfly/react-topology is still conflicting but must wait till upgrade to PF5.

Motivation for the change:

Preparing for React 18 upgrades. Just splitting #726 into smaller issues/tasks for easy tracking.
