Description of problem:

Instruction to use must-gather for hosted clusters is incorrect. Current instruction is:

oc adm must-gather --image=registry.redhat.io/multicluster-engine/must-gather-rhel8:v2.x /usr/bin/gather hosted-cluster-namespace=HOSTEDCLUSTERNAMESPACE hosted-cluster-name=HOSTEDCLUSTERNAME

However, the image to be used for MCE 2.5 and later apparently is registry.redhat.io/multicluster-engine/must-gather-rhel9:v2.x, where x should be modified to the minor version for MCE.

So, for MCE 2.6 (ACM 2.11) the correct instruction should be:

oc adm must-gather --image=registry.redhat.io/multicluster-engine/must-gather-rhel9:v2.6 /usr/bin/gather hosted-cluster-namespace=HOSTEDCLUSTERNAMESPACE hosted-cluster-name=HOSTEDCLUSTERNAME

The other example command in the same section must also be fixed.

This is in accordance to the instructions of section 1.10.2.2, which demonstrates how to use must-gather for MCE.
