E2E Test CI Flag Logic

[Sepehr-Sobhani]

Describe the task

Currently, we use the if: ${{ inputs.is_nx_affected }} flag in our e2e tests to bypass test runs when no changes are detected in a particular frontend app. However, this approach does not account for changes made in the backend code, particularly in the e2e test setup and fixtures. As a result, when backend-related changes occur, the flag fails to recognize that e2e tests might still be impacted, leading to missed issues that are only noticed in the next PR. This behavior introduces the risk of undetected problems.
