BUILD-960: Update Containers to UBI9 go-toolset

- Update Dockerfiles to use the ubi9 go-toolset images. For the
  releaser image, this avoids downloading the go sdk as part of the
  relase process.
- Add `build-container` make target for convenience.
- Update ci-operator build root to use rhel-9 golang 1.20 image for OCP
  4.15
