DS E2E plugin tests are using upstream che-samples, with x86_64 UDI image only:

• https://gitlab.cee.redhat.com/codeready-workspaces/e2e-codeready/-/blob/latest/files/devfiles/plugins/VscodeXmlPluginDevfile.ts#L14
• https://gitlab.cee.redhat.com/codeready-workspaces/e2e-codeready/-/blob/latest/files/devfiles/plugins/VscodeYamlPluginDevfile.ts#L14
  ...

We need to change DS E2E plugin tests to use downstream samples, which are using multi-arch UDI image https://quay.io/repository/devspaces/udi-rhel8 :

• https://github.com/crw-samples/web-nodejs-sample/tree/devspaces-3.0-rhel-8

It is also blocking sun the tests against IBM Z / Power Dev Spaces.
