CI Workflow - PR Sentinel

[rafaeltonholo]

• Verify if the PR contains linked issues
• Verify if the PR follows the commit guidelines from Git Commit Guide
• Verify if the PR's title follows the Conventional Commits style - better for changelogs
• Check if the AI Disclosure was filled
• Autoclose PRs that do not follow the PR template
• Update both PR template and Contribution guidelines document to ensure PR title enforcement is well documented.
• Check if a merge commit is present; if present, fail sentinal and ask OP to use rebase instead.
