Hint for Tanzu skip verify wrong

[timdeluxe]

The "false" default hint here:

cloudcontrol/feature/kubernetes/feature.yaml

Line 45 in 6786e44

* Environment TANZU_SKIP_TLS_VERIFY: Skip TLS verification [false]

is wrong, since the logic works on a "yes"/"no" base, see here:

cloudcontrol/feature/kubernetes/install-tanzu.sh

Line 20 in 6786e44

if [ "X${TANZU_ADD_CONTROL_CLUSTER:-no}X" == "XyesX" ]

so the hint has to be rather "no" than "false".
