The image is going to be pushed after the next commit.

You can use make trigger_ci to push an empty commit.

If you also want to run E2E tests, please add devnet-test-e2e label.

The CI will now also run the e2e tests on devnet, which increases the time it takes to complete all CI checks.

You may need to run make trigger_ci to submit an empty commit that'll trigger the tests.
