RepoUpdater: Convert ConcurrentRefUpdateException into LockFailureException

Calling the RepoCommand may fail with a ConcurrentRefUpdateException
that represents a LOCK_FAILURE. Convert this exception into a
LockFailureException so that our auto-retrying logic for LOCK_FAILURES
can recognize the LOCK_FAILURE and retry the operation, instead of
failing immediately.

Example stacktrace:
update for foo/manifest:*:default.xml (Repo) => foo/superproject:* (ref refs/heads/main) failed: org.eclipse.jgit.api.errors.ConcurrentRefUpdateException: Cannot lock refs/heads/main. Ensure that no other process has an open file handle on the lock file refs/heads/main.lock, then you may delete the lock file and retry.. RefUpdate return code was: LOCK_FAILURE
