Fixes #43316

`gemma3/gemma3n` and `modernbert/modernbert_decoder` require different rope parameters per layer type, which expects `rope_parameters` to be a dictionary with two keys `sliding_attention` and `full_attention` mapping to `RopeParameters` containing `rope_type`.

This PR updates the typing hints for these models and sets the new format dectection stricter.

Could you run `make fix-repo` @Tcc0403 to make CI happy?

Just checked https://app.circleci.com/pipelines/github/huggingface/transformers/160922/workflows/639eb1c9-7c5a-41a8-aebe-7ff9dd377abb/jobs/2117913

Do I have to fix modeling files to match modular files?

@Tcc0403 no worries, I will rebase main and check the `repo bot` again. We just noticed the bot wasn't working and your PR became a testbed 😅 

@bot /repo

The docs for this PR live [here](https://moon-ci-docs.huggingface.co/docs/transformers/pr_43320). All of your documentation changes will be reflected on that endpoint. The docs are available until 30 days after the last update.

Everything works, will merge when torch issues are resolved which arent related to the PR
