[e2e] TestSystemInternalTLS set min-scale to not lose logs

[maschmid]

• set min-scale in TestSystemInternalTLS to not lose the queue-proxy logs

Sporadically, downstream we see TestSystemInternalTLS failing with

    system_internal_tls_test.go:110: TLS not used on requests to queue-proxy: pods "system-internal-tls-mjhqutwi-00001-deployment-6b84b959d7-mjkcs" not found

so here we set min-scale: 1 , same as it's already done in TestTLSCertificateRotation for the same reason.
