Warning about deprecate `set-output` command still visible in `v1.0.8`

[kimlep01]

Hi, I updated my workflow to use v1.0.8 and I'm still seeing two warnings about set-output. I created a new issue because no one reacted to my earlier comment.

My repo:

Run joerick/pr-labels-action@v1.0.8

Found label  do-not-merge 
  Setting env var for remaining steps: GITHUB_PR_LABEL_DO_NOT_MERGE=1

Action output:
labels: " do-not-merge "
labels-object: {"do-not-merge":true}
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/
