I am trying to fetch the last and latest build numbers or build job ids and save them into the text files like old_build_number.txt contains the last successful build number or id and new_build_number.txt contains the all build Ids as build_number - status example as given below from the Jenkins after the Build Job successful by using the trigger-jenkins-build.yml triggered through the GitHub Actions.
And the GitHub URL GitHub Project URL , YAML file trigger-jenkins-build.yml and GitHub Action Results.

And the old_build_number.txt, new_build_number.txt files are created under the folder .github/build_numbers as given the links above.
I am not sure what went wrong to update the text files after the successful Jenkins build job.
Resetting the repo after you save the files wipes out your changes
git reset --hard origin/${GITHUB_REF#refs/heads/} || { echo "git reset failed"; exit 1; }
