It seems Azure DevOps are deprecating "Node 6" and giving a warning for the tasks using the old way

##[warning]This task uses Node 6 execution handler, which will be removed March 31st 2022. If you are the developer of the task - please consider the migration guideline to Node 10 handler - https://aka.ms/migrateTaskNode10 (check this page also if you would like to disable Node 6 deprecation warnings). If you are the user - feel free to reach out to the owners of this task to proceed on migration.

Let me know if you need help to migrate this.

Thank you for this great project.
