[CI] Add PR title format checker

### Describe the enhancement requested

- Either MINOR: or GH-NNN.
- If GH-NNN, check for closing keywords in body and if not present, add them.
- We can validate components too?

Start by locating the repository's existing CI and pull-request validation configuration. Determine how PR titles and bodies are currently checked, then clarify whether component validation is required. Done means titles follow MINOR: or GH-NNN, and GH-NNN pull requests include a closing keyword in the body.
