Make the e2e Tests actually not blocking (#39175)

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/39175

Just `tee`-ing the e2e tests command into a log is not enough to make the command non-failing.
I'm wrapping it into a single command and `or`-int to true to ensure that it never fails.

## Changelog:
[Internal] - Make e2e tests not failing in CI
