[xtreme-s] Update Minds14 results
# What does this PR do?

Updated results for the XTREME-S experiments with the new Minds14 splits
_The documentation is not available anymore as the PR was closed or merged._<|||||>Let's maybe put the new eval code (to do per lang eval) directly into this here as well?<|||||>@patrickvonplaten The per-language results are now reflected in the model card too: https://huggingface.co/anton-l/xtreme_s_xlsr_300m_minds14 (will update the MLS results after running one more full experiment).
The names look a bit janky due to how metrics are parsed by the trainer, but overall the PR is ready to merge :slightly_smiling_face: <|||||>Perfect! Thanks for fixing this :-)
