Final update of doctest
# What does this PR do?

Fix the remaining doc examples. The doc example in `feature_extraction_markuplm` is un-fixable (unless we remove the example), so not added to the list for testing.

Follow up PR of #22268 and  #22292
There is a style issue for `src/transformers/models/bertweet/tokenization_bertweet.py`. Will check it tomorrow instead. Sorry.<|||||>_The documentation is not available anymore as the PR was closed or merged._
