Changes

Fixes 🐛

• Send Tekton installation namespace to EL (#929)

The EventListener did not have knowledge of which namespace Triggers was installed in. Instead it always assumed it was tekton-pipelines leading to the bug described in #923.
This PR fixes by having the Reconciler send the installation namespace as a environment variable set on the EventListener's pod.
