Add CICD

[maorcc]

We want CICD (Continuous Integration and Continues Deployment)

Notes:

1. CICD should support both the BE and the FE.
2. Use GitHub Actions
3. For now, any successful merge to Main branch should be deployed to production.
4. Any code that is pushed to the GitHub should automatically run tests and Lint.
5. Failing tests or failing Lint should prevent the merge to Main.
