Description

Resolve #467

Update bump-license-year.yml to use environment file instead of deprecated set-output command. For more information, see: https://github.blog/changelog/2022-10-11-github-actions-deprecating-save-state-and-set-output-commands/

I found the workflow files that use set-output command through the following command:

$ find .github/workflows -name '*.yml' | xargs egrep '\bset-output\b'

AS-IS

run: |
  echo "::set-output name=year::$(date +'%Y')"

TO-BE

run: |
  echo "year=$(date +'%Y')" >> $GITHUB_OUTPUT
