Generates warning about set-output command being deprecated

[scouten-adobe]

I used this action in a recent workflow and it generated a warning:

Warning: 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/

Release v5.0.0-beta includes an update from @dusda to use the latest version of actions/core which internally uses the new method to set outputs.

Confirmed fixed in our project. Thank you!
