Add a precommit hook to automatically update .ci/docker/ci_commit_pins/pytorch.txt when torch_pin.py is changed.

[larryliu0820]

This pull request introduces a new script, .github/scripts/update_pytorch_pin.py, which automates the process of updating the PyTorch commit pin based on the nightly version specified in torch_pin.py. The script parses the nightly version, fetches the corresponding commit hash from the PyTorch nightly branch using the GitHub API, and updates the pin file accordingly. This automation helps ensure that the CI environment uses the correct nightly commit for PyTorch.

Automation of PyTorch nightly pin updating:

• Added .github/scripts/update_pytorch_pin.py, a script that reads the nightly version from torch_pin.py, parses the date, fetches the corresponding commit hash from the PyTorch nightly branch via the GitHub API, and updates .ci/docker/ci_commit_pins/pytorch.txt with the new hash.

Test plan:

Run .githooks/install.sh
Tested manually by changing NIGHTLY_VERSION and try to commit locally. Was able to see .ci/docker/ci_commit_pins/pytorch.txt being updated.

Feel like it is helpful. Developers will have to do some manual install to enable this.

LGTM!! I can get rid of my CI #15070
