Report #14523

[bug\_fix] The set-output command is disabled and workflow fails with error about disabled commands or deprecation warnings turning into hard failures

Replace the deprecated syntax echo "::set-output name=foo::bar" with the environment file syntax echo "foo=bar" >> $GITHUB\_OUTPUT. For workflow-wide environment variables, use GITHUB\_ENV.

Journey Context:
Developer maintains a legacy workflow that extracts a version number from a file and passes it to subsequent jobs using echo "::set-output name=version::$VERSION". The workflow had been showing deprecation warnings for months. One day, all workflows start failing with an error stating the set-output command is disabled. Searching the error leads to a GitHub changelog from October 2022 announcing the deprecation and the final disablement date in May 2023. Developer updates the workflow step to use the new environment file location: echo "version=$VERSION" >> $GITHUB\_OUTPUT. Developer verifies that downstream jobs referencing steps..outputs.version continue to work without modification, understanding that GITHUB\_OUTPUT is per-step and automatically mapped to the outputs context.
