fix(gitutils): Use the GitHub-based package in release-main GitHub Actions

[Copilot]

release-main now runs the repository package through GitHub-based resolution with npm settings that let the script execute successfully, while keeping the gitutils installation and verification flow intact.

• Workflow execution path

  • Use the GitHub-based package spec for release-main instead of npx.
  • Add --legacy-peer-deps so the package install can run install.sh without failing on workspace peer resolution.
  • Keep the same failure handling and alias verification flow.

• Stub parity

  • Apply the same command change to the gitutils workflow stub so deployed workflow copies stay aligned.

- name: Install GitUtils
  run: npm exec --yes --legacy-peer-deps --package github:tomgrv/devcontainer-features -- devcontainer-features -- gitutils

Keep using Github-based package, but make sure it runs smoothly

Updated in af87950 to use the GitHub-based package again, with an explicit npm exec --package github:tomgrv/devcontainer-features -- devcontainer-features -- gitutils invocation in both workflow copies.

Script execution does nothing and exits with error code 1. Looks like install.sh is not called

Updated in c1b4386 by adding --legacy-peer-deps so the GitHub-based package install runs install.sh instead of failing during npm workspace peer resolution.
