Add a GitHub job which executes `cargo aduit` to verify whether the newly created commit does not contain problematic dependencies

Currently, we do not have the check for pull request whether it contains problematic dependencies. We should check newly included dependencies before it is merged into our code base. Therefore, we need to add a job to execute a cargo audit before merging it to maintain our code health.
