Log expected errors related to conflicts in RebaseWorker without tracking in Sentry

There are a lot of events in Sentry from Rebaseworker

For example: https://new-sentry.gitlab.net/organizations/gitlab/issues/1520647

Gitlab::Git::Repository::GitError: 9:rebasing commits: rebase: commit "29f9c69f180a6eb4d576a148b58c9f23a7541ed8": there are conflicting files.

These are handled gracefully here by logging the error and tracking in Sentry: https://gitlab.com/gitlab-org/gitlab/-/blob/master/app/services/merge_requests/rebase_service.rb#L37-39

Proposal:

• Only log the error without also tracking in Sentry reduce noise in Sentry
