TFDS load creates directory literally named "~"

Repro snippet:

Please cd into a directory that is NOT your home directory ~ before running

tfds.load(name="caltech_birds2011", shuffle_files=True)

Result: a directory literally named '~' is created in the current directory, in addition to the ~/tensorflow_datasets directory that is correctly created in the user's home dir . Files are then created under this bizarre '' dir making them very difficult to locate. This seems to be happening during the decompression or tfrecords generation process.

• Operating System: Linux (Vertex AI Workbench default)

• Python version: 3.6

• tensorflow-datasets/tfds-nightly version: 4.6.0

• tensorflow/tf-nightly version: 2.9.1

• Does the issue still exists with the last tfds-nightly package (pip install --upgrade tfds-nightly) YES

Start at the tfds.load(name="caltech_birds2011", shuffle_files=True) entry point and trace the decompression or TFRecord-generation path described in the report. Reproduce from a directory outside the home directory; done means no literal '~' directory is created and generated files remain under ~/tensorflow_datasets.
