Upgrade Angular Version from 1.8.0 to 1.8.3 due to Vulnerability Issue in Community/Frontend-ng Application

As part of our ongoing commitment to maintaining a secure and robust software infrastructure, we need to address a vulnerability issue in the Community/Frontend-ng application. The current version of Angular being used is 1.8.0, which has known security vulnerabilities. To mitigate these risks and ensure the application's stability, we need to upgrade the Angular version to 1.8.3.

The following steps should be followed to complete this upgrade:

1. Perform a thorough review of the project's codebase and dependencies to identify any potential conflicts or issues that may arise during the upgrade process.
2. Update the package.json file to reflect the new Angular version as a dependency and specify the required version as 1.8.3.
3. Update any other dependencies or packages that may be affected by the Angular version upgrade to ensure compatibility and avoid conflicts.
4. Run thorough unit tests to ensure that the application's functionality remains intact after the upgrade. Address any failing tests and fix any issues that may arise.
