Checksums for the dataset imagenette has changed

Does the issue still exist with the last tfds-nightly package (pip install --upgrade tfds-nightly)?

• Yes

Reproduction instructions

!rm -r ~/tensorflow_datasets/imagenette/
!rm -r ~/tensorflow_datasets/downloads
import tensorflow_datasets as tfds
tfds.load('imagenette')

Start by reproducing the failure with the shown cleanup commands and tfds.load('imagenette'). Compare the downloaded imagenette2.tgz checksum with the expected value reported in the error; the issue is done when loading imagenette succeeds with the current artifact checksum.
