chore: update e2e-test-utils to 2.1.0 for coverage image swap

Version 2.1.0 includes the automatic __coverage image swap logic
from PR redhat-developer/rhdh-e2e-test-utils#95 (merged 2026-06-04).

Changes:
- Auto-fixture _coverageCollector that collects window.__coverage__
- Automatic swap to __coverage images when E2E_COLLECT_COVERAGE=true
  and plugin role is frontend-plugin

This enables E2E coverage collection to work end-to-end.
