Update the version of rules_python to 0.31.0 and add py_repositories() call in WORKSPACE file

[PankhudiJ17]

• BUILD INFORMATION:

Repository: io
Tag: v0.37.1
Python Version(s): Tested with Python 3.10.11 and 3.11.3
Operating System: Linux (ppc64le architecture)
                  NAME="Ubuntu"
                  VERSION="22.04.5 LTS (Jammy Jellyfish)"
Architecture: ppc64le
Bazel Version: 6.5.0
TensorFlow Version: 2.16.1
Build Command: bazel build -s --verbose_failures $BAZEL_OPTIMIZATION --copt="-Wno-error=array-parameter=" --copt="-I/usr/include/tirpc" //tensorflow_io/... //tensorflow_io_gcs_filesystem/... --cpu=ppc

• We are attempting to build tensorflow/io on the ppc64le architecture but encountered an error related to the Python repository:

ERROR: /root/.cache/bazel/_bazel_root/7e563aa8f1493c3ba33faa85b32d7a3c/external/python/BUILD.bazel:10:6: no such package '@python_ppc64le-unknown-linux-gnu//': The repository '@python_ppc64le-unknown-linux-gnu' could not be resolved: Repository '@python_ppc64le-unknown-linux-gnu' is not defined and referenced by '@python//:python_headers'

• This error occurs because the repository @python_ppc64le-unknown-linux-gnu is not defined, causing Bazel to fail when attempting to resolve Python dependencies.
  We have tested building TensorFlow IO with both Python 3.10.11 and Python 3.11.3 and encountered the same issue.

• Temporary Solution/Workaround:
  We resolved the issue by updating the version of rules_python from 0.23.1 to 0.31.0 and explicitly adding the py_repositories() call in the WORKSPACE file.

• Here are the changes we made:
