Remove continue-on-error from e2e test in GHA (#51746)

Summary:
Pull Request resolved: #51746

I observed that when continue-on-error is set to true, Github reports the outcome of a job as success even if it fails.

With this change, we should ensure that when an E2E test fails, the pipeline fails, so that we can retry the jobs properly.

## Changelog:
[Internal] - Remove continue-on-error from e2e tests in GHA
