Add pre-commit hooks to the repository

Currently, the only way to force linting in a PR is via Github Action scripts. However, with so many PRs being raised we should be using pre-commit hooks so that these linting checks run before doing a commit.
This will help keep the git tree much cleaner by removing the need for all the commits just doing linting fixes.

Start by inspecting the repository's GitHub Action scripts and existing linting checks to understand what currently runs for pull requests. Determine how those checks should be represented as pre-commit hooks and verify that the hooks run before commits while the existing PR validation remains effective. Done means the repository documents and supports the new hooks without lint-only follow-up commits.
