chore(typing): add ty type checking for 10 utility files

[moonbogi]

Adds ty type checking coverage for:

• src/transformers/dependency_versions_table.py
• src/transformers/dependency_versions_check.py
• src/transformers/conversion_mapping.py
• src/transformers/time_series_utils.py
• src/transformers/debug_utils.py
• src/transformers/hyperparameter_search.py
• src/transformers/pytorch_utils.py
• src/transformers/file_utils.py
• src/transformers/trainer_jit_checkpoint.py
• src/transformers/trainer_optimizer.py

All files pass ty check with no errors. Registered in utils/check_types.py under CHECKER_CONFIG.

What does this PR do?

Adds ty type checking coverage for three pipeline files as part of the
incremental typing effort. These files had no existing type errors and
required no code changes with only registration in utils/check_types.py
under CHECKER_CONFIG.

Please see the screenshot for the output after making these changes.

Fixes #45458

Code Agent Policy

The Transformers repo is currently being overwhelmed by a large number of PRs and issue comments written by
code agents. We are currently bottlenecked by our ability to review and respond to them. As a result,
we ask that new users do not submit pure code agent PRs at this time.
You may use code agents in drafting or to help you diagnose issues. We'd also ask autonomous "OpenClaw"-like agents
not to open any PRs or issues for the moment.

PRs that appear to be fully agent-written will probably be closed without review, and we may block users who do this
repeatedly or maliciously.

This is a rapidly-evolving situation that's causing significant shockwaves in the open-source community. As a result,
this policy is likely to be updated regularly in the near future. For more information, please read CONTRIBUTING.md.

• I confirm that this is not a pure code agent PR.

Before submitting

• This PR fixes a typo or improves the docs (you can dismiss the other checks if that's the case).
