Updating override parameter step in GitHub actions

I am looking for an experienced technical professional to help update the override parameter step in my Github Actions workflow. I am currently using Version 3 of Github Actions and need the override parameter step updated. The current value of the step is unspecified. This should be a relatively simple task for an experienced developer, so I am confident the right professional can handle this project. If you have any additional questions, please don't hesitate to reach out. Thank you!
