Bump stale bot version

[eladkal]

stale workflow shows warning message:

The `set-output` command is deprecated and will be disabled soon. Please upgrade to using Environment Files. For more information see: https://github.blog/changelog/2022-10-11-github-actions-deprecating-save-state-and-set-output-commands/

https://github.com/apache/airflow/actions/runs/4153778955

lets try to update to latest version and see if it's resolved.

I went though the change log and looks like we can just update the version without changing anything else. They added close-issue-reason but the default value of not not_planned seems OK.
