[docs] TGF4K8s Hello World Guide will need to be updated

[pnikonowicz]

I was going through some gemfire 4 k8s documentation and was trying to get the hello world instruction to work. I noticed that the gfsh command does not work when trying to connect to the loopback interface via localhost. But the gfsh command does work when I use the hostname of the machine. Is this something that should be updated in the docs? Thanks

Hey Paul! Thanks for letting us know about this. I've shared the details for this issue as well as #1789 with the appropriate teams and we should get that content updated to be current and correct. Thanks!

This guide will need to be updated once the next version of the GemFire for k8s product is GA.
