kind-dev-cluster script is getting the wrong ROUTER_IMAGE_TAG

[nluaces]

When e2e tests are being executed in a release, the kind-dev-cluster script is not getting the configured router version in the variable ROUTER_IMAGE_TAG, and is using instead SKUPPER_ROUTER_IMAGE that is not set in the Makefile.

As a result, the tests are being executed with the skupper controller image that is being released and the main skupper-router version by default.

@nluaces one part of this I think you could be missing: that script is not ran by make presently.

Right, it is referenced in config.yml my mistake.
