CI: Add conventional commit checker

[ObstinateM]

Contributor: Mathis Beauville

Description: This pull request adds a new job to the existing GitHub Actions workflow to ensure that all commits follow the "Conventional Commit" format. The commit types are dynamically loaded from a commit_type.json file, allowing for easy customization and future scalability.

Main Changes:

• Added a new job to the existing GitHub Actions workflow to check commit messages.
• Integrated a custom python script to check commit message.
• Commit types are loaded from a commit_type.json file, making it easier to update and manage allowed types.

Linked Issue: #6

Testing:

The new job was tested to ensure proper validation of commit messages and correct loading of commit types from commit_type.json. If a commit doesn't comply with the specified format, the workflow will fail, and an error message will be returned. (see test/failing branch)

Instructions:

After this PR is merged, contributors must ensure that their commits follow the "Conventional Commit" format, with types as defined in commit_type.json. Non-compliant commits will result in PR failure during validation.
