Consolidate e2e test image references and add apply-tags task (#421)

* Consolidate e2e test image references and add apply-tags task

- Update e2e test image path to use maestro/maestro-e2e for consistency
- Simplify image retrieval in Makefile to use latest tag
- Remove dynamic tag lookup logic from GitHub workflows
- Add apply-tags task to Tekton pipelines for both PR and push workflows
- Update all workflow references to use consolidated image path

* Revert workflow changes to longrunning.yml and manual-e2e.yml

Restore dynamic image SHA resolution for e2e test workflows instead of using :latest tag.
This reverts the workflow file changes from commit 190dfe4.

 If you want to push the image to your OpenShift cluster default registry and then deploy it to the cluster. You need to follow [this document](https://docs.openshift.com/container-platform/4.13/registry/securing-exposing-registry.html) to expose a default registry manually and login into the registry with podman. Then run `make push` to push the image to the registry.
