cicd: close upon merge for forks has no secret access

[scottschreckengaust]

Describe the bug

When a pr is closed from a fork, it does not have access to the github action secrets. So the github command line fails.

Expected Behavior

When a PR closes the github cli can run:

  env:
    GH_TOKEN: ***

Current Behavior

When a PR closes the secrets is unavailable:

gh: To use GitHub CLI in a GitHub Actions workflow, set the GH_TOKEN environment variable. Example:
  env:
    GH_TOKEN: ${{ github.token }}
Error: Process completed with exit code 4.

Reproduction Steps

Run a pr from a branch and merge (it closes and runs the github cli command successfully)

Possible Solution

Change the trigger from pull_request to pull_request_target (need to consider the risks)
