Track potential change to OpenJSF Code of Conduct

[achrinza]

There has been some discussion on the CoC in the OpenJSF with regards to a silent change in Contributor Covenant v2.1 and some wording.

There's also discussion surrounding changing the CoC handling requirements for OpenJSF projects.

This issue is to track this potential change so that we can update our CoC to match OpenJSF's changes.
