cannot pass `/` in bucket name

[mschrimpf]

The tutorial example uses "brainscore-storage/brainio-brainscore" as the bucket name.

vision/brainscore_vision/data/ferguson2024/data_packaging/data_packaging.py

Line 58 in 118df8f

stimulus_set_identifier=stimuli.name, bucket_name="brainscore-storage/brainio-brainscore")

This however throws an error:

Invalid bucket name "brainscore-storage/brainio-brainscore": Bucket name must match the regex "^[a-zA-Z0-9.\-_]{1,255}$"
