Bad label for removing deployment in domain

In domain mode, Deployments => Content Repository, when a content is not deployed it should be possible to remove it. The option is available but under label Undeploy instead of Remove.

It turned out that the change is intentional, see HAL-1908. Hence just the DomainContentRepositoryDeploymentTest#removeDeployment test of the tests-hal-deployment module in testsuite.next. needs to be updated.
