Improve releasing to the BCR

- It is recommended to not use compatibility_level until there is a
  concrete reason
- Dependencies in MODULE.bazel should be the minimum requirements, not the
  latest available versions. Thus, do not keep in sync with the WORKSPACE
  approach. In WORKSPACE, dependencies can overwrite each other and thus
  providing more flexibility (and problems).
- We configure a proper presubmit check
