When using github actions, it is possible to output variables.
From reading the documentation there is no way to do it when using self-hosted infrastructure. This has also been confirmed by support.
Theres a lot of different use cases where this is useful.
e.g. aws-actions/configure-aws-credentials, cycjimmy/semantic-release-action and tj-actions/changed-files actions to name just a few.
This would also massively help with potential migration from GHA onto Harness CI.
