Follow up to breaking change PR patternfly/patternfly-react#9094

[Description of the breaking change the rules needing to be created]

Required actions:

1. Build codemod
2. Build test
3. Update readme with description & example

Closing this as we don't need a codemod unless we are reordering event params or adding a param to an existing list of params - confirmed with @gitdallas
