Merge branch 'kn/ref-batch-output-error-reporting-fix' into jch

A handful of code paths that started using batched ref update API
(after Git 2.51 or so) lost detailed error output, which have been
corrected.

* kn/ref-batch-output-error-reporting-fix:
  fetch: delay user information post committing of transaction
  receive-pack: utilize rejected ref error details
  fetch: utilize rejected ref error details
  update-ref: utilize rejected error details if available
  refs: add rejection detail to the callback function
  refs: skip to next ref when current ref is rejected
  refs: drop unnecessary header includes
