Sanity Checklist

• I have updated the GitHub Issue assignees, reviewers, labels, project, iteration and milestone
• For docs, I have run make docusaurus_start
• For code, I have run make go_develop_and_test and make test_e2e
• For code, I have added the devnet-test-e2e label to run E2E tests in CI
• For configurations, I have update the documentation
• I added TODOs where applicable

[github-actions]

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.
