Deploy new GitLab Chart version

Please deploy a version of GitLab Chart that includes gitlab-org/charts/gitlab!1949 (merged). Ideally we want it on pre environment ASAP and then staging and prod as time permits (together with %14.0 rollout I guess).

Notable things:

• New TCP/HTTP port is exposed on the Service (8154). It's then used by the Ingress for the /k8s-proxy path on the kas.gitlab.com domain.
• New TCP/gRPC port is exposed on the Pods (8155). Used for kas Pod to Pod communication.
• New Secret is autogenerated. Used as JWT signing secret for authn on the above endpoint.
