Current behavior

The deploy.yml workflow requires the creation of a GH_TOKEN secret.

Expected behavior

At the start of each workflow run, GitHub creates a related secret named `GITHUB_TOKEN. Related doc here

What is the motivation / use case for changing the behavior?

By renaming the name of the secret, it would prevent a manual step when using the schematic to add this workflow.

Others:

Once accepted as a valid change, I will communicate to encourage people to submit a PR.

Why do you need the deploy.yml?
