* Update Jenkins Plugins to Resolve Dependency Issues

The update of three plugins seem to be having issues from the update list, the below plugin versions seem to run into the dependency issues :
generic-webhook-trigger:2.2.2,
github-oauth:611.v70d151e60ec4 ,
slack:741.v00f9591c586d

Updated Jenkins plugins to specific versions to resolve dependency issues.

Each plugin version was tested and verified to work without introducing any dependency conflicts.
