Add Dinov2 with registers

[BernardZach]

What does this PR do?

This PR is a continuance of #32905 by @NielsRogge.

When running pytest there were two errors:

ERROR examples/research_projects/codeparrot/scripts/tests/test_deduplicate.py
ERROR templates/adding_a_missing_tokenization_test/cookiecutter-template-{{cookiecutter.modelname}}/test_tokenization_{{cookiecutter.lowercase_modelname}}.py

I am not sure what the problem for these are. Any guidance would be appreciated.

Hi @BernardZach could you add me as a collaborator to your branch? Will push some fixes

[BernardZach]

@NielsRogge I believe I added you in the correct spot. Let me know if there are any issues.

Hi @BernardZach I've investigated the issue, when running the modular converter, it changes the modeling code in a non-equivalent way, causing various tests to fail. I've pinged @Cyrilvallez about it

Hi all, I was wondering if there are any updates on this PR?

[NielsRogge]

Fixed all tests :) Hmm for some reason my push made this PR closed. My branch is here: https://github.com/huggingface/transformers/compare/main...NielsRogge:add_dinov_2_registers_innovationcore?expand=1.

I wanted to push it here by doing git push innovationcore main but for some reason that closed your PR. The issue might be that you're working on the main branch - normally a PR is never on the main branch

I've set you as remote, git remote -v gives:

innovationcore  git@github.com:innovationcore/transformers.git (fetch)
innovationcore  git@github.com:innovationcore/transformers.git (push)
