Add new event types

[bitwiseman]

See https://issues.jenkins-ci.org/browse/JENKINS-57430

GitHub has added new events since this library was created. The new events result in an exception being thrown for webhooks:

java.lang.IllegalArgumentException: No enum constant org.kohsuke.github.GHEvent.CHECK_RUN

I don't have a list of event that need to be added aside from CHECK_RUN and CHECK_SUITE, but I'm sure there are more.

Bump

Among other things this limits usage in Jenkins.

I am hitting this issue in Jenkins now too

It is being worked on.
