Add PyTorch 1.11 to past CI
# What does this PR do?

Add PyTorch 1.11 to past CI (as PyTorch 1.12 is the current latest version).

I will re-run past CI once this PR is merged (for [this comment](https://github.com/huggingface/transformers/issues/18181#issuecomment-1189047657)).
_The documentation is not available anymore as the PR was closed or merged._
