MGMT-21001: Refactor assisted-events-stream CI config to stop pinning Go versions

• Switch build_root to from_repository: true, building the root image from the repo’s Dockerfile.
• Drop the base_images stanza and the inputs block that referenced release:golang-1.21.
• Regenerate and commit the updated presubmit job YAML via make update.

This keeps the CI environment in sync with the Go version declared by the project and removes the need for future hard-coded bumps in openshift/release.
