`GH action` : Use GITHUB_OUTPUT instead of set-output in github actions

### Expected Behaviour

save-state and set-output commands used in GitHub Actions are deprecated and [GitHub recommends using environment files](https://github.blog/changelog/2023-07-24-github-actions-update-on-save-state-and-set-output-commands/).

This PR updates the usage of set-output to $GITHUB_OUTPUT

Instructions for envvar usage from GitHub docs:

https://docs.github.com/en/actions/using-workflows/workflow-commands-for-github-actions#setting-an-output-parameter

### Actual Behaviour

#### Platform and Version

#### Sample Code that illustrates the problem

#### Logs taken while reproducing problem

Search the repository's GitHub Actions workflow files for the deprecated set-output usage, then read the surrounding workflow steps and the linked GitHub documentation. Done means the affected outputs use GITHUB_OUTPUT and the workflows remain valid; no specific test file is mentioned, so validate the workflow configuration as far as the repository permits.
