Need additional line in config file, to work tutorial's example.

I'm afraid to say, I wrote bellow 'additional line' in ' elasticsearch/config/elasticsearch.yml
', to work tutorial's example about 'Updating Documents' by 'script'.
So, it is needed to add an explanation in tutorial.

// additional line
script.groovy.sandbox.enabled: true

// error
{
"error" : "ElasticsearchIllegalArgumentException[failed to execute script]; nested: ScriptExceptio
n[dynamic scripting for [groovy] disabled]; ",
"status" : 400
}

Thanks @nesah I just added a note mentioning that dynamic scripting needs to be enabled in order for the script based update to work.
