[Feature Request] Test the usage of GitHub new feature for configuration variables in workflows (POC)

### Description

# Context

From the documentation:

Previously, you needed to store this configuration data as encrypted secrets in order to reuse values in workflows.
While extremely secure, this method did not allow for easy storage and retrieval of non-sensitive configuration data such as compiler flags, usernames, server names etc.

Configuration variables allows you to store your non sensitive data as plain text variables that can be reused across your workflows in your repository or organization.
You can define variables at Organization, Repository or Environment level based on your requirement.

# Requirement

- Explore usage of this new feature whether it will add value to our workflow configurations. Example: moving away from secrets for strings that are not secrets
