Fix: Update optimization.py (#44909)
* Update optimization.py
The `get_scheduler` function was identifying the `inverse_sqrt` scheduler type but failing to pass `**scheduler_specific_kwargs` to the underlying `get_inverse_sqrt_schedule` function.
This caused user-defined parameters like `timescale` to be silently ignored. This commit adds the missing kwargs to the function call at line 664.
