RHCLOUD-44853: Update pipeline to use v2 ConfigMaps and remove chrome sidecar (#737)

* Update pipeline to use v2 ConfigMaps and remove chrome sidecar

Update the pull request pipeline to align with the new shared konflux
pipeline definition that removes the insights-chrome-dev sidecar.

Changes:
- Remove chrome-port parameter (was 9912)
- Rename test-app-port to e2e-app-port
- Remove test-app-name parameter
- Update frontend-proxy-routes-configmap to use -v2 suffix
- Update pipeline reference to catastrophe-brandon/konflux-pipelines commit fda9a7ea
- Remove taskRunSpecs section (sidecar configuration now handled by pipeline)

The new architecture routes all requests directly to the application
container, simplifying the pipeline execution.

* fix: add hostAliases for stage.foo.redhat.com in E2E tests

Add hostAliases configuration to properly resolve stage.foo.redhat.com
to localhost in the E2E test pod. This is the Kubernetes-native way to
configure /etc/hosts entries.

Without this configuration, getent hosts stage.foo.redhat.com fails
and the E2E tests cannot connect to the frontend-dev-proxy sidecar.
