newer transformers library versions break olmo3, fix provided in a PR

I submitted the following PR against transformers: https://github.com/huggingface/transformers/pull/45945

OLMo 3 scaled RoPE handling was broken by a some sweeping change refactoring RoPE handling. As a result, using a model such as `allenai/Olmo-3-1025-7B` produces incorrect outputs. I tested this by measuring the Olmo3 paper table 3 results and can see that using f.ex. transformers 5.5.3, the table 3 cannot be reproduced. However, I re-measured with my fix and the results seem to be fixed if I use a transformers version that includes my fix.

Would anyone from Ai2 be willing to review the change in the above PR?
