chore(ci): use correct github credentials for pushing (#28806)

The update-package-lock job did not configure Git credentials correctly.
As a result, the job is unable to push the `package-lock.json` changes
to the repo:
https://github.com/ionic-team/ionic-framework/actions/runs/7476310958/job/20346663176

This PR configures the job with the correct credentials.
