Use SDK for E2E tests

Describe the bug When running the e2e test, the script uses az - the Azure CLI to clean up the resources. However, we can't expect all developers of ng deploy to have the Azure CLI installed. The cleanup should be done using the resources that are already available - the SDKs that are used in the project.

Error: ./scripts/test.sh: line 44: az.cmd: command not found To Reproduce Steps to reproduce the behavior:

1. If you have Azure CLI, uninstall it. (Run az to see that it's not available)
2. Run npm run test:e2e
3. If the tests run as expected, after getting the link of the website, it crashes with the error message above.
4. Click on the link - it opens the website. Meaning the resources were not cleared.

Expected behavior 3 - the test script should not crash. 4 - the link should not be available.
