docs: update contributing checks

[waketzheng]

Description

Update the contribution guide to mention pre-commit run --all-files as an alternative way to run automated style and lint checks alongside make check.

Motivation and Context

The repository already provides a .pre-commit-config.yaml and documents pre-commit install in the development setup flow.
Mentioning pre-commit run --all-files gives contributors a clearer way to manually run the configured hooks across the project.

How Has This Been Tested?

Ran:

• git diff --check
• pre-commit run --files docs/CONTRIBUTING.rst

Checklist:

• My code follows the code style of this project.
• My change requires a change to the documentation.
• I have updated the documentation accordingly.
• I have added the changelog accordingly.
• I have read the CONTRIBUTING document.
• I have added tests to cover my changes.
• All new and existing tests passed.
