Replaced community.kubernetes with kubernetes.core in the openshift4_aws workshop

[tarexveff]

The community.kubernetes Ansible collection has been hard-deprecated in favor of kubernetes.core. This pull request replaces all occurrences of community.kubernetes with the recommended kubernetes.core replacement within the openshift4_aws workshop directory path.

Thanks! We're working on this across all the module names, in all the workshops.

Hello! Is there anything we can do to get the two PRs, this one #183 and #181 merged? It may be there is some overlap? We've been running with local fixes in our fork waiting for this to merge, in particular the kubernetes.core FQCN changes.

Thanks!

Sorry, there aren't as many folks using these, since the original support team was blown up, 2 years ago. We can try to see if we can get it done. But, we could use someone who wants to be a new maintainer.
