chapter 9 ELK stack fails when using recommended 4.1.1 version of geerlingguy.elasticsearch role

[Jecks]

following the book at version 2.0 August 5, 2020 chapter 9 ELK example is asking to pull version 4.1.1 of elasticsearch role. this results in failure to start elasticsearch with error :

Unrecognized VM option 'UseConcMarkSweepGC'
Error: Could not create the Java Virtual Machine.

which you already encountered in https://github.com/elastic/elasticsearch/issues/62716 and that you resolved in later version of the role

using 5.1.0 version of the role seems to fix the issue

Thanks, looks like I'll need to bump the versions in the book example!
