[CI/CD] Block pull requests if the PR title and commit messages do not meet the required standards

[Rwatana]

Issue Number

Implementation Summary

This pull request introduces a CI/CD pipeline check to ensure that pull requests (PR) are only merged if their titles and commit messages adhere to predefined standards. This includes validating formatting, structure, and any additional criteria specified in the repository's guidelines.

Scope of Impact

This check will be executed during the CI/CD pipeline for each pull request. It will enforce stricter commit and PR title standards, improving overall commit message quality and repository maintainability.

Particular points to check

Ensure the validation logic correctly identifies titles and commit messages that do not conform to the standards. Confirm that the implementation does not interfere with other parts of the CI/CD pipeline or existing workflows.

@Rwatana I’m considering changing from shell to script. Is that feasible? I’d like to do the same for other repositories as well.
