Resolve #1062

Update continuous-integration-workflow.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: |
  # Run jobs if in upstream repository
  echo "::set-output name=runjobs::true"
  # Extract version from gradle.properties
  version=$(cat gradle.properties | grep "version=" | awk -F'=' '{print $2}')
  echo "::set-output name=project_version::$version"

TO-BE

run: |
  # Run jobs if in upstream repository
  echo "runjobs=true" >> $GITHUB_OUTPUT
  # Extract version from gradle.properties
  version=$(cat gradle.properties | grep "version=" | awk -F'=' '{print $2}')
  echo "project_version=$version" >> $GITHUB_OUTPUT
