StackSet config file with errors

[asantos-fuze]

Hi,

In the documentation for rain stackset deploy we are pointed to an example file test-config.yaml that has a syntax error, making the file unusable for StackSetInstances settings.

On

rain/test/samples/test-config.yaml

Line 149 in 251173d

StackSetInstanses:

it should be StackSetInstances instead of StackSetInstanses that currently is on the file.
Currently StackSetInstances config will fail on this function:

rain/internal/cmd/stackset/stackset_deploy.go

Line 236 in 251173d

func isInstanceConfigDataValid(c *cfn.StackSetInstancesConfig) bool {

if we don't update to StackSetInstances
