(SIMP-9239) Add GHA workflows to rubygem-simp-rspec-puppet-facts

[op-ct]

This patch adds standardized GitHub Actions to provide GitHub-based CI/CD workflows. Among this first batch are:

• PR GLCI - Auto-trigger corresponding GLCI (if actor has write perms)
• Manual: PR GLCI - Team members can trigger corresponding GLCI for a PR
• PR GLCI Cleanup - Clean up any auto-triggered GLCI pipelines/branches

This patch also enforces the standardized asset baseline using simp/puppetsync, and may apply other updates to ensure conformity.
