Fix check of unecessary packages (issue #37626)
Author: HichTala
Pull request: yes

# What does this PR do?
This pull request updates the `get_imports` function in `src/transformers/dynamic_module_utils.py` to improve how conditional imports are handled. The most important change introduces a check for functions in `transformers.utils.import_utils` to ensure imports in specific conditional blocks are ignored.

### Enhancements to conditional import handling:

* [`src/transformers/dynamic_module_utils.py`](diffhunk://#diff-955cd5ce55aed4805a0875320c92ae20f0e80d86f010bb30e0ef267376c75d1cR154-R168): Added a reference to `transformers.utils` and updated the logic in the `recursive_look_for_imports` function to ignore imports in conditional blocks that use functions from `transformers.utils.import_utils`, in addition to the existing check for `is_flash_attn` functions.

Hi @HichTala. thanks for the updates. This looks good now, so I'm going to merge!

My pleasure

I think, yesterday one of the test didn't pass, I'm not sure of want changed, can you enlighten me ? 😅

hi @hichtala, that was probably just a flaky test! I reran the tests and it passed afterwards. We're working on making the CI more robust so that stops happening

Hi @Rocketknight1, ok notted thank you :+1:
