Allow upgrading the Knative GitLab Managed Application

Similar to https://gitlab.com/gitlab-org/gitlab-ce/issues/49384 we should allow upgrading Knative helm chart.
Intended users
Further details
Should note that last time this was discussed the helm chart itself did not support upgrades. Perhaps this is no longer true and we should investigate.
