ci: enable e2e distributed tests in GitHub Actions

Re-enable e2e tests to run on CI with continue-on-error flag.
This will show the current status of LocalCluster/OTP 28 compatibility
issues without failing the workflow.

Tests are expected to timeout due to known :peer module issues in OTP 28,
but this allows monitoring for when the issue is resolved upstream.
