ci: add new pr title requirement workflow

[pascal-arevalo]

Rationale

Introduces a GitHub Actions workflow to enforce a standardized format for Pull Request titles across the organization.

All PR titles must follow the conventional commits specification and additionally end with AB#<HU-ID>, where <HU-ID> is the Azure DevOps task ID associated with the work. For example:

feat(routes): add new /users route to merchant users [AB#123](https://dev.azure.com/wompi-co/e4538663-13b6-40f0-948d-94024707b88f/_workitems/edit/123)
