As written on https://github.blog/changelog/2022-10-11-github-actions-deprecating-save-state-and-set-output-commands/:

Action authors who are using the toolkit should update the @actions/core package to v1.10.0 or greater to get the updated saveState and setOutput functions.

This currently cause github actions using this action to issue a 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/
