Protocol: bumping to v14.8
Taken from Gitaly v14.8.2, the most notable difference for us is the removal of the `CommitService.CommitsBetween` RPC method. As we've had problem with grpcio/grpcio-tools 1.44, we're pinning to 1.42, the same version used in the Rails application in GitLab 14.8. This does change the resulting stub modules.
